Figure 76 Regular synthetic backup
Figure 76 on page 262 shows a situation where a synthetic backup was performed
after each incremental backup. This strategy enables the simplest and quickest restore
to the latest possible state, or to any earlier point in time that was backed up. Only
one element is required for restore, namely the synthetic full backup of the desired
point in time.
Figure 77 Synthetic backup and object copy
In Figure 77 on page 262, a synthetic backup was performed and then copied. This
provides additional safety. The restore to the latest possible state can use any of the
three different restore chains shown. By default, Data Protector selects the optimum
restore chain, which normally includes the synthetic full backup or its copy. In case
of missing media, a media error, or similar, an alternative restore chain is used.
How data protection periods affect restore from synthetic backup
Data protection of a conventional full backup and all incremental backups that precede
synthetic full backup does not compromise a successful restore.
