Recover -s MyNetworkerServer -S 74637438882 -iY > c:\copy.log 2>&1
OK so let's analyse that statement:
Recover
Refers to the fact that we are trying to do a recovery, and 'recover.exe' will be the executable you see running in task manager.
-s
Specifies the name of the Networker server, replace this with the name of your Networker server.
-S
Defines the 'save set number'. You may have to get this from your Networker administrator or the backup logs or backup log emails that the system publishes each day.
-iY
This refers to the conflict resolution option. The actual switch is -i and in this case the 'Y' means 'yes overwrite' other selections can be found in the library below.
Obviously the '> c:\copy.log' is telling the executable to redirect the output to a permanent log instead of the screen and, as always in DOS, the '2>&1' tells the redirect to capture both 'std.out' and 'std.error'.
Here is the rest of the library for 'RECOVER'

DESCRIPTION
recover browses the saved file index and recovers selected files from
the NetWorker system. The file index is created in the backup index
namespace when files are saved with save(8). If files are saved into
an index-storing archive pool using nsrarchive(8), the file index is
created in the archive index namespace. When in interactive mode (the
default), the user is presented with a view of the index similar to a
UNIX filesystem, and may move through the index to select and recover
files or entire directories. In automatic mode (-a option), the files
specified on the command line are recovered immediately without brows-
ing. While in save set recover mode (-S option), the save set(s) spec-
ified are retrieved directly without browsing the NetWorker file index.
Use of save set recover mode is restricted to root.
When using recover without the -S option, users who are root may
recover any file. The remaining permission checking rules described in
the paragraph apply to users who are not root. For files that don't
have an Access Control List (ACL), the normal Unix mode bits must allow
you to read the file in order to recover it. Files with an ACL can
only be recovered by their owner or by root.
If path argument is used with the save(8) command and one of the
directories in the path is a symbolic link, then the target path of the
symbolic link must be specified with -a option to recover the files.
Recovering the files by specifying the symbolic link in the path with
-a option will result in " not in index" message. Alternatively,
-S option may be specified to recover these files.
Concurrent recoveries can be performed from an advanced file type
device (adv_file), either by using multiple -S options to identify mul-
tiple save sets, or executing multiple recover commands concurrently.
OPTIONS
-a Specifies automatic file recovery with no interactive browsing.
Path specifies one or more files or directories to be recovered.
Symbolic links are not followed, though the link file itself
will be recovered. Mount points are also not followed unless
the most recent save(8) was performed with the '-x' option.
-S ssid[/cloneid]
Specifies save set recover mode and can only be used by root.
This mode can be used to implement fast batch file recovery
without requiring the NetWorker file index entries. ssid speci-
fies the save set id's for the save set(s) to be recovered.
When there are multiple clone instances for a save set, the
cloneid can also be specified to select the particular clone
instance to be recovered from. When no path arguments are spec-
ified, the entire save set contents will be recovered. One more
or more path's can be specified to limit which directories and
files are actually recovered. If path's are supplied, then the
beginning of each path name as it exists in the save set must
exactly match one of the path's before it will be recovered.
Shell like file name matching using meta characters like `*',
`?', and `[...]' is not done. You can use a path that ends in
with a slash (`/') to force a directory only match (e.g., use a
path of /etc/fs/ instead of /etc/fs to prevent files like
/etc/fsck from being recovered as well).
-d destination
Specifies the destination directory to relocate recovered files.
Using this option is equivalent to using the relocate command
when in interactive mode (see usage). Relative paths are inter-
preted relative to the current working directory.
-s server
Selects which NetWorker server to use.
-J storage-node
Specifies which host to use as the storage node for the recovery
(see nsr_storage_node(5)).
-c client
Client is the name of the machine that saved the files. When
browsing a directory that was saved by another client, the path-
names will reflect the file tree of the client that saved the
files. By default save and recover determine the client name
from the filesystem table. This option might be necessary if
the -L option was used on the save command. This option cannot
be used in conjunction with the -S ssid option (save set recover
mode).
-x index-namespace
Browse/recover files in the specified file index namespace. By
default the backup namespace is used. The other recognized index
namespace is: archive. This field is case sensitive.
-p pass-phrase
Specifies an additional pass phrase to use when attempting to
recover files backed up using the aes directive. By default the
current datazone encryption key is tried as well as the key gen-
erated from the default pass phrase. Using this option causes
recover to generate an encryption key from the pass phrase and
try it if the default and datazone pass phrase keys do not work.
This option can be specified multiple times.
-t [ date | "l locale_date" ]
Display/recover files as of the specified date. The date speci-
fied can be in nsr_getdate(3) format, or locale_date format when
"l locale_date" is specified. Note that the surrounding quotes
and a blank space after "l" are required for locale_date format.
Using this option is equivalent to using the changetime [-l]
command with the given date or locale_date when in interactive
mode (see usage). This option cannot be used in conjunction
with the -S ssid option (save set recover mode).
For example, -t date specifies date/time in nsr_getdate (3) for-
mat. -t "l " specifies date/time in the locale
format.
See changetime for more information on the locale_date format
supported.
-q Turns off the verbose output. The recover command normally runs
with verbose output.
-f Forces recovered files to overwrite any existing files whenever
a name conflict occurs. This is the same as specifying -iY.
-n Does not write or create any files or directories when recover-
ing.
-i {nNyYrR}
Specifies the initial default overwrite response to use when
recovering existing files. Only one letter may be specified.
This option is the same as the uasm -i option when running in
recover mode. See the uasm(8) man page for a detailed explana-
tion of this option. For directed recovers (see the -R option),
only 'N', 'Y', and 'R' are valid values.
-I input file
Takes the paths to recover from the command line, and read paths
to recover from the named file. The paths must be listed one
per line. If no paths are specified on the command line, then
only those paths specified in the file will be recovered. To be
used in conjunction with -a option.
-R recover-target
Specifies the name of the remote machine to direct the recovery.
This is used in conjunction with the -c option to specify brows-
ing of another client's index. When the -R option is used,
either the -f or the -i option must also be specified in order
to instruct the recover target what to do when it is recovering
existing files. Note that the values 'N', 'Y', and 'R' are the
only valid ones to use with the -i option for directed recovers.
Note also that the -a option is not supported with the -R
option.
-N system save set
Used to recover the following system save sets: SYSTEM DB, SYS-
TEM FILES, or SYSTEM STATE. (Windows Only)
-u Stops when an error occurs during recovery. Normally, recover
treats errors as warnings and tries to continue to recover the
rest of the files requested. However, when this option is used,
recover will stop recovering on the first error it encounters.
This option is not valid for directed recovers.
USAGE
When using recover in the interactive mode, an image of the filesystem
at a particular time is presented. Using commands similar to the
shell, you can change the view and traverse the filesystem. Files may
be selected for recovering, and the actual recover command issued.
The following commands manipulate the view of the filesystem and build
the list of files to recover. In all of the commands that take a name
argument pattern matching characters can be used. The pattern matching
characters and regular expression format are the same as for the UNIX
shell sh(1).
ls [ options ] [ name ... ]
List information about the given files and directories. When no
name arguments are given, ls lists the contents of the current
directory. When a name is given and name is a directory, its
contents are displayed. If name is a file, then just that file
is displayed. The current directory is represented by a '.'
(period). The options to this command correspond to those of
the UNIX command, ls(1). An additional recover specific -S
option can be used to select the save time instead of the last
modified time for sorting (with the -t option) and/or printing
(with the -l option). Files that have been added to the recover
list are preceded by a '+'. Files that have an ACL have a
trailing '+' (e.g. -rw-r--r--+) after the mode bits when view-
ing file details.
lf [ name ... ]
is the same as ls -F. Directories are marked with a trailing
'/', symbolic links with a trailing '@', sockets with a trailing
'=', FIFO special files with a trailing '|', and executable
files with a trailing '*'.
ll [ name ... ]
is the same as ls -lgsF. Generates a long format listing of
files and directories. This command can be used to find the
value of a symbolic link.
cd [ directory ]
Change the current working directory to [ directory ]. The
default directory is the directory recover was executed in. If
directory is a simple symbolic link, cd will follow the symbolic
link. However, if directory is a path containing symbolic links
anywhere but at the end of the path, the cd command will fail;
you should cd a component of the path at a time instead.
pwd Print the full pathname of the current working directory.
add [ name ... ]
Add the current directory, or the named file(s) or directory(s)
to the recover list. If a directory is specified, it and all of
its descendent files are added to the recover list. Symbolic
links are not followed, though the link file itself will be
recovered. Mount points are also not followed unless the most
recent save(8) was performed with the '-x' option.
debug [ level ]
Turn on or turn off debugging. Level must be a number. If level
is 0, debugging is off. As the debug level goes higher, the
recover command prints out more messages. By default, debugging
is off.
delete [ name ... ]
Delete the current directory, or the named file(s) or direc-
tory(s) from the recover list. If a directory is specified,
that directory and all its descendents are deleted from the
list. The most expedient way to recover a majority of files
from a directory is to add the directory to the recover list,
and then delete the unwanted files.
dir [ w ] [ filename... ]
This command is similar to the "ll" command with the following
differences. The dir command uses the display format used by
"dir" command in DOS command prompt. Also this command does not
add a + to the files selected for recovery. With w option, the
names of the files or directories only are displayed.
list [ -l ] | [ -c ]
Display the files on the recover list. With no arguments the
recover list is displayed as a list of full path names, one per
line, followed but a total count of the files to be recovered.
The -c argument prints just the total count of files to be
recovered. The -l argument prints the files in the same format
as the ll command with the -dS options.
volumes
Prints a list of the volumes needed to recover the current set
of files on the recover list. If all volumes are near-line
(near-line volumes are available volumes that are not mounted),
this command will note that all volumes needed are near-line.
If all volumes are on-line (on-line volumes are those that are
available and mounted) or if some volumes are on-line and some
are near-line, this command will note that all volumes are on-
line. Both near-line and on-line volumes do not require manual
intervention.
recover
Recover all of the files on the recover list from the NetWorker
server. Upon completion the recover list is empty.
verbose
Toggle the status of the 'verbose' option. When verbose mode
is on, recover displays information about each file as it is
recovered. When verbose mode is off, recover only prints infor-
mation when a problem occurs. The default is verbose mode on.
force If name conflicts exist, overwrite any existing files with
recovered files.
noforce
Cancel the force option. When in 'noforce' mode, a prompt is
issued each time a naming conflict arises between a file being
recovered and an existing file. At each prompt, six choices are
presented: 'y', 'Y', 'n', 'N', 'r' and 'R'. To overwrite the
existing file, select 'y'. To rename the file to an automati-
cally generated alternative name, select 'r'. Selecting 'n'
causes the recovered file to be discarded. The capital letters
invoke the same action for all subsequent conflicts without fur-
ther prompting. Hence, selecting 'Y' will cause all existing
conflicting files to be overwritten, 'N' will cause all con-
flicting recovered files to be discarded, and 'R' will automati-
cally rename all conflicting recovered files (except when an
external ASM has a conflicting file name that already ends in
the rename suffix).
relocate [ directory ]
Change the target recover location to directory. If directory
is not specified then the user will be prompted for a destina-
tion directory. Relative paths are interpreted relative to the
current working directory within the recover program.
The recovered files will be placed into this directory, which
will be created if necessary. When files from multiple directo-
ries are being recovered, they will be placed below this direc-
tory with a path relative to the first common parent of all the
files to be recovered. For example, if /usr/include/sys/errno.h
and /usr/include/stdio.h are being recovered, and the relocation
directory is set to /tmp, then the first common parent of these
two files is include, so the recovered files will be named
/tmp/sys/errno.h, and /tmp/stdio.h.
destination
Print destination location for recovered file.
exit Immediately exit from recover.
help Display a summary of the available commands.
? Same as help.
quit Immediately exit from recover. Files on the recover list are
not recovered.
versions [ name ]
All instances of the current directory, if name is not speci-
fied, or the named file or directory, found in the NetWorker
file index are listed. For each instance, three lines of data
are displayed. The first line is similar to the ll output. The
second line lists the instance's save time. The third line
specifies which tape(s) this instance may be recovered from.
With appropriate use of the changetime command, any one of the
entries may be added to the recover list. As with ls, lf, and
ll, files that have been added to the recover list are preceded
by a '+'.

DIAGNOSTICS
Recover complains about bad option characters by printing a ``usage''
message describing the available options.
Message from server: other clones exist for failed save set
The request failed on a save set that had multiple clones. The
server automatically picks a different clone on each attempt.
Recover automatically re-submits its recover request to the
server, if any files remain to be recovered.
Path name is within machine:export-point
An informative message that lets you know that the given path
name is mounted from a network file server and that the recovery
will use the index for the named file server. If the machine is
not a NetWorker client, then the -c option may be necessary.
Browsing machine's on-line file index
An informative message that explicitly states which NetWorker
client's index is being browsed for interactive recovers that
resolve to another machine.
Using server as server for client
An informative message that lets you know which NetWorker server
was selected for client's index.
Cannot open recover session with server
This message indicates that some problem was encountered con-
necting to the NetWorker server on the named machine.
error, name is not on client list
This message indicates that the client invoking the recover com-
mand is not in the server's client list. See nsr_service(5) for
details.
path: Permission denied
The file name cannot be recovered because you are not root, and
you don't have read permission for the file.
path: Permission denied (has acl)
The file name cannot be recovered because you are not root, the
file has an ACL (Access Control List), and you are not the owner
