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.
