HP B6960-96035 - Manual (Page 104)

• Description: uniquely defines the backup objects with identical client name and
mount point.
• Type: backup object type, for example filesystem or Oracle.
The way in which a backup object is defined is important to understand how
incremental backups are done. For example, if the description of a backup object
changes, it is considered as a new backup object, therefore a full backup will be
automatically performed instead of incremental.
Examples of backup options
You can customize the backup behavior for each individual backup object by
specifying the backup options for this object. The following are examples of the
backup options you can specify:
• Logging level of information going to the IDB.
Data Protector provides four levels that control the amount of details on files and
directories stored in the IDB:
• Log All
• Log Files
• Log Directories
• No Log
Note that changing the level of stored information affects the ability to browse
the files using the Data Protector user interface when restoring. For more
information on logging levels, see “
Logging level as an IDB key tunable
parameter ” on page 199.
• Automatic load balancing
Dynamic device allocation from a specified list. For more information, see “ How
load balancing works ” on page 156.
Data Protector dynamically determines which object (disk) should be backed up
to which device.
• Pre-exec and post-exec scripts
Processing to prepare a client for a consistent backup. For more information, see
“
Pre-exec and post-exec commands ” on page 223.
You can also specify the directories to exclude from a backup, or back up specific
directories only. You can also back up disks as they are added. Thus, your backup
is fully configurable and dynamic.
