Figure 30 Full backup with mixed incremental backups
This policy takes into account the fact that there are not many changes during
weekends. Data is backed up using a combination of simple incremental backups
and Incr1 (differential) backups to optimize backup performance. To restore files
from Thursday’s backup, you need to provide media from the full backup and the
second Incr1 backup, that is, two media sets.
Automated or unattended operation
To simplify operation and the operator’s involvement in the backup process, Data
Protector provides extensive functionality supporting unattended or automatic backup
during lights-out time. This section describes how to plan your scheduling policies,
how these policies influence the behavior of backup, and provides examples of
scheduling policies. This section focuses on longer periods of unattended operation
spanning from several days to weeks, rather than the unattended operation during
a single backup.
Considerations for unattended backups
Data Protector provides simple ways of scheduling your backups. Since the
effectiveness of scheduling policies depends on your environment, you need to plan
before finding the best scheduling policy.
