Backup Exec 20.1: Synthetic Backup questions

[mk128935]

Hi,

I appreciate the feedbacks to these questions on synthetic backup. 

Q1: Is there any recommended hardware spec for synthetic backup on top of the recommendations for Backup Exec?

Q2: Are there any sample benchmarks on synthetic backup? Ex. for this server, with this amount of data, synthetic backup took this amount of time...

Q3: Error handling during a synthetic backup. What happens when a hardware error, etc. occurs during a synthetic backup and it gets interrupted? Does the original full backup file get corrupted and become unusable? Or is a separate file created during synthetic backup and therefore, the original backup file is retained? If this is the case, does it mean that extra capacity is consumed other than the backup size?

There is not specific hardware requirements for Synthetic backup that go beyond the normal Backup Exec requirements.

The synthtec backup is catalog driven and there are more catalog comparison done for the inrementals.

There is not really any benchmarks due to many factors.  The amount of files/directories and particually size of files can affect the perormance in any type of Backup method.

Generally if there is some type of "catalog" related error/issue during a incremental it will trigger a full to run.... yes this could could take up more space on your storage.

Keep in mind you need the FULL (Baseline) on your storage device plus all the incrementals to create the new Synthetic (Full) on a storage device.
