Volume Group and Logical Volume backups are only available on Linux systems if
LVM (Logical Volume Manager) is installed. Meta-disk backups are only available
on Linux if meta-disk (Software RAID) support is installed.
TSM Edition allows only System (-t S) backups.
System Backups: When performing a System Backup (S), the data is a list of volume groups
(AIX or Linux) or ZFS Pools (Solaris) to include on the backup. For AIX systems, the rootvg
volume group is always included, so it need not be specified. In that case, if no volume groups
are specified, only the rootvg volume group is included. On Linux systems, this option only
applies if LVM is implemented on the system and there are volume groups configured. If no
volume groups are specified, then no volume group data (including filesystems and raw logical
volumes) will be included on the backup. Whether AIX, Linux or Solaris, you may specify “all”
to include all available volume group (or zpools in the case of Solaris) data. Note, however,
that raw volume data (volumes that do not include filesystems) will also be included unless you
specify the –n option.
The –l (incremental level) may be specified to indicate that only files which have changed
since the last prior level backup should be included. Level 0 indicates that all files should be
backed up and is used as a base for all subsequent incremental backup levels. Level 0 may be
specified with a System Backup to indicate that this backup should act as a full incremental
from which latter incremental levels may be applied.
Backups may run faster when using a larger buffer size (-b option) than the default of 64
Kbytes. If the tape device supports a larger than 64 Kbyte buffer, increasing this value will
often cause backups to run faster. Try buffer sizes that are a power of 2, such as 128K, 256K
and 512K. This value will only support up to 1024 Kbytes (1 Megabyte).
If a server is specified with the –s option, you must have first configured the backup device
where the backup will be stored. Refer to
stserver and stvdev to configure servers and
devices.
The stbackup command will exit with a completion message and one of the following exit
codes:
0 Success
1 Backup
failed
2 Pre-backup failure (no data written)
6 Non-bootable System backup created (warning - backup completed)
7 Cannot overwrite tape
9 Internal program error
11 Possible incomplete backup (warning - backup completed - verify required)
99 Killed by user (Ctrl-C)
