• 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 Table 26 on page 326:
