The restore command is similar to the Solaris ufsrestore command, except
that the restore command doesnt support the i function key of ufsrestore.
This function key enables you to specify interactively individual files and directories to
be restored from a tape. However, you can restore individual files and directories
using the x argument of the filer restore command.

If you want to restore all files in a backup using the restore r command, you must
begin the restoration from a level 0 backup. You can, however, restore a specified file
or directory from an incremental backup tape when you use the restore x
command.

The filer supports up to three simultaneous restore commands.

This section describes the requirements that you must meet for the
restore com-
mand to be completed successfully.
The space required for the restore command to be completed is about
100 MB more than the amount of data to be restored. The command terminates
if it runs out of space. If you want to perform a full restore, the additional space
should be in the directory that is the root of the backup. If you want to restore
only some data in a backup, the additional space should be in the
/etc/tmp direc-
tory of the volume where data is to be restored.
The restore command does not restore qtree information. Before you restore
a volume containing qtrees, create the qtrees. Refer to Performing a Full
Restore of a Volume Containing qtrees for the procedure for restoring qtrees.
Before you perform a full restore, make sure that the directory into which you
restore data does not contain the restore_symboltable file. The restore com-
mand uses the restore_symboltable file for incremental restores and for
resuming an interrupted restore. If the restore_symboltable file exists in the
directory because of an unsuccessful restore, remove the file before starting the
full restore, or the full restore fails.

You can enter the restore command through the console or through rsh. Entering
the restore command through rsh gives you these benefits:
When the restore command is in progress, you can still use the console to
manage the filer.
You can start multiple restore commands through rsh.
