Storix Software SBAdmin User Guide - Manual (Page 20)

Each backup job will be assigned a unique Backup ID , and each client backup within the job will have a
unique backup sequence number . Each TSM backup will have a unique name on the server, so there is no
danger of overwriting a prior backup. Instead, the user must expire TSM backups manually to prevent
excessive use of disk space. When doing so, not only the backup labels, but also the actual backup objects
are removed from the TSM server. The administrator may also set the
overwrite policy so that a TSM
backup that has aged over a certain number of days, or exceeded a certain number to retain, is
automatically expired and removed when the same backup job is re-run. These options will help limit the
amount of space on the TSM server required to store backups while ensuring that the latest backups are
kept.
Backup status, output, and label information may be displayed for TSM backups just as with tape backups.
Understanding Backup Types
There are many types of backups that may be performed using SBAdmin. The backup type is configured into
the
backup profile , which is why you must have at least one profile setup for each type of backup you want to
perform. The backup types are as follows:
1. System Backup - This backup contains the operating system and optionally all user data. User data
may be only files in mounted filesystems, or may also contain raw data found in logical volumes
(AIX/Linux), partitions (Linux), meta-disks (Linux/Solaris), disk slices (Solaris) or ZFS volumes
(Solaris). It is possible to reinstall the entire system from a System Backup, or even use the backup of
one client to install another. Select files, directories, logical volumes and volumes groups, and even
raw data may be restored from a System Backup. For information the system installation process, refer
to the
SBAdmin System Recovery Guide .
AIX: The System Backup contains the rootvg volume group, and may optionally contain some or all of
the other volume groups on the system. If the backup is performed to the beginning of a tape, then the
tape is also configured to boot to the System Installation process.
2. Volume Group Backup – This backup is typically used to separately backup the LVM volume groups
that are not part of the operating system. Files or logical volumes within the volume group backup may
also be backed up incrementally, including only files or logical volumes that have changed from a prior
backup. The backup may contain one or more volume groups, and an entire volume group may be
recreated (AIX) and/or restored from the backup. Individual files, directories, filesystems or raw logical
volumes may be recreated (AIX) and/or restored.
Volume Group backups are only available for AIX and for Linux systems with LVM installed.
3. Filesystem Backup - This backup will contain one or more filesystems on the system. The filesystems
may be built on any logical volume (AIX/Linux), partition (Linux), slice (Solaris), or meta-disk
(Solaris/Linux). ZFS filesystems are also supported on Solaris systems. Files within the filesystems
may also be backed up incrementally, including only files that have changed from a prior backup.
Specific files directories or filesystems may be recreated (AIX) and/or restored from this backup.
4. Logical Volume Backup - This backup may include one or more "raw" logical volumes. From this
backup, only an entire logical volume may be recreated (AIX) and/or restored. Logical volume backups
are only available for AIX and for Linux systems with LVM installed.
5. Directory Backup - This is the only backup type common to most other backup applications. It includes
any number of directories and files, and select files and directories may be restored.
6. Partition Backup (Linux systems only) - This backup may include one or more "raw" partitions typically
containing non-filesystem data. From this backup, only an entire partition may be restored.
7. Slice Backup (Solaris systems only) – This backup may include one or more “raw” disk slices typically
containing non-filesystem data. From this backup, only an entire disk slice may be restored.
