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.
