You can use the Backup Wizard to back up data interactively. To maximize the speed of the backup, you can back up data to a group of parallel backup media. You can use up to 32 tape devices to reduce backup times significantly.
If possible, we recommend that you back up data to a group of parallel backup media, rather than backing up the data to a single backup medium with succeeding media. You cannot make log backups in parallel.
Always check the database structure before each complete data backup (see Checking Database Structures).
There are multiple backup devices available.
You
have created the required backup media.
If you want to
perform a backup using an automatic tape loader (Backups to Automatic
Tape Loader), or with the help of external backup tools(Backups with External
Backup Tools), then you must state this specifically when defining the
media.
Under normal circumstances, you should backup database
instances in the
ONLINE operational
state.
You can also backup
database instances in the
ADMINoperational state, but only in exceptional
circumstances.
Use the Backup Wizard.
1. If you have not yet created a group of parallel backup media, do this now as described in Creating a Group of Parallel Backup Media. Select a group of parallel backup media in the window Media for Backup.
2. Check the information, and change it, if necessary ( Changing Backup Media).
3.
Only for
database systems up to version 7.3 (inclusive):
If you want to perform a
data backup, now choose whether the backup is to be performed for Recovery orMigration.
Recovery : Data backup for restoring the database instance
if errors occur
Migration: Data backup with
checkpoint; that is, to migrate the database instance
For more information about checkpoints, see the User Manual: SAP DB
7.3.
4.
Start the
backup.
If the capacity of
the specified group is not large enough for the backup and you are not using
an automatic tape loader, the Backup Wizard asks you to specify and insert a
new backup medium as soon as the previous medium has been filled (see
Backups with Manually Changed Media).
