232 Backup, restore, and recovery
Starting FSE restore
The fserestore command
To start FSE restore, run the fserestore command on the FSE server. The command performs all steps of
the restore process. Common synopsis of the fserestore command is the following:
The option --file selects backup image stored in the file BackupFileName on disk as the restore
source, and the option --device selects a backup image stored on tape as the source for backup image
retrieval or actual restore.
When tape is selected as the restore source, by default, the most recent backup image stored on the
backup FSE medium is used for retrieval or performing actual restore. Using the option ––offset, you
can direct fserestore to use an older backup image for either operation.
If either of the options --count and --retrieve-to is specified, fserestore only copies the
selected backup images to disk. The argument CountNumber specifies how many backup images will be
copied, and the argument DirectoryPath specifies the destination directory. If --count is specified
and --retrieve-to is omitted, the backup images will be copied to FSE disk buffer.
For additional information on the fserestore command, see the fserestore man page.
Examples of restoring from disk
The FSE restore process will use the backup image stored on the share
\\backup–server\backup_share under the name backup_image.tar.bz2 as the restore source.
In this example, the FSE server is running on a Windows host:
The FSE restore process will use the backup image stored on the file system /mnt/backup under the name
backup_image_file.tar.bz2 as the restore source. In this example, the FSE server is running on a
Linux host:
Examples of restoring from tape
The FSE restore process will use latest backup image stored on tape medium as the restore source. It will
use the backup FSE medium loaded in the drive with SCSI ID 0:1:0:0. In this example, the FSE server is
running on a Windows host:
The FSE restore process will use the third most recent backup image stored on tape medium as the restore
source. It will use the backup FSE medium loaded in the drive with control device /dev/sg4. In this
example, the FSE server is running on a Linux host:
Examples of retrieving backup images from tape
The FSE restore process will not perform actual restore, but will only copy the latest backup image stored on
tape medium to the share \\storagedepot\backup_images. It will use the backup FSE medium
loaded in the drive with SCSI ID 0:3:0:0, and will report target location of the backup image in the FSE
disk buffer. In this example, the FSE server is running on a Windows host:
fserestore -–file BackupFileName
fserestore ––device DeviceFile
[––offset OffsetNumber [––count CountNumber]]
[––retrieve–to DirectoryPath]
C:\>fserestore --file \\backup–server\backup_share\backup_image.tar.bz2
# fserestore --file /mnt/backup/backup_image_file.tar.bz2
fserestore –-device id:0:1:0:0
fserestore –-device /dev/sg4 --offset 3
fsebackup --device id:0:3:0:0 --offset 1 --count 1 --retrieve-to
\\storagedepot\backup_images
