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
.
