The -i “sequence” option is used to specify which backup to verify or restore when
multiple backups are stacked onto the same tape or series of tapes. If this flag is
specified, and the value is greater than 1, the tape or tapes will be automatically
forwarded to the beginning of the desired backup before verifying or restoring
data.
The -F flag must be specified to allow restoration of system directories or files that
are not ordinarily replaceable. Restoring files to these directories can have adverse
affect on the system or even cause a system failure, and should be used with
extreme caution. Those directories are:
v /
v /dev
v /etc/vg
v /etc/objrepos
v /usr
v /usr/lib
v /usr/lib/objrepos
Specifying a new destination: The -D “destination” option indicates that the data
should be restored to the new destination.
When you restore from a file/directory backup, the files or directories will be
restored relative to the specified destination but will include the full path of the
original files. For instance, if a file /home/tony/file1 is restored to destination /tmp,
the resulting file would be /tmp/home/tony/file1.
When you restore from a system, volume group or filesystem backup, the files are
restored to the destination directory, but the filename does not contain the prior
mount point of the filesystem. For instance, if files are restored from the /home
filesystem to the /tmp destination, a file previously called /home/tony/file1 will be
restored as /tmp/tony/file1.
To restore logical volume data to a new location, specify a new logical volume
name. The specified logical volume name cannot be currently active.
Incremental Restores: The -y flag must be specified to enable restoration of
incremental data. To restore the entire contents of an incremental backup, this flag
must be specified. The resulting filesystems will contain the same files as it did at
the time the backup was created. This can, in some cases, require files to be
re-removed from the filesystem that were deleted prior to the incremental backup
level being performed.
If the -y flag is not specified, you can restore only select files and directories from
an incremental backup. Refer to “Understanding Incremental Backups” on page 4-1
for important details on restoring data incrementally.
Notes:
1. This command is not intended for restoring an entire AIX operating system.
The only way to restore the entire system is to reinstall from the system
backup. Refer to Chapter 12, “System Installation and Maintenance”, on page
12-1.
2. When specifying the files to restore, SysBack supports the use of BRE (Basic
Regular Expression) wild cards to restore a wildcard match of files. The files
and the wildcard must be enclosed in double quotation marks (″) to avoid
