• Backup Specifications
Configure backup specifications as follows:
• DB_A...G
Backup specifications for each of the 7 IDBs and configuration files. Schedule
the backup specification such that Data Protector will run a weekly full backup
and a level one incremental every day, except Sundays at 03.00.
Why use differential (incr1) backups?
• To restore the latest data only two media sets need to be accessed, one
for the latest full backup and one for the latest level 1 incremental backup
prior to the restore point-in-time. This considerably simplifies and speeds
up the restore. Where simple incremental backups are used, the number
of media sets may increase considerably, making the restore process more
complex and slower.
Two copies of the IDB and configuration files should be made, for security
reasons.
• SAP_A...C
Backup specification for the SAP database servers in cells A, B and C,
respectively. Use the staggering approach to avoid network load, device load,
and time window issues as depicted in
