Enable Automatic Backup Integrity Checks ?

[dstreufe]

Can anyone tell me what the "Enable Automatic Backup Integrity Checks" checkbox does? I realize it does some kind of integrity check, but I am trying to assess the pros/cons of this and possible performance impacts... So I am more specifically wondering exactly what this "integrity check" involves.


Thanks,
Dan

Hello Dan. If this option is selected, Veeam Backup will perform the integrity check of backup file in the beginning of each incremental run. This typically takes just a few seconds, and so does not impact performance noticeably. Starting v4, Veeam Backup features transactional storage with some level of redundancy. The verification process leverages this redundant data to verify the user data integrity which can be affected due to issues like abnormal job termination, failed disk write and so on. During this process, if any issues are found, the backup file is automatically recovered to the last known good state before initiating the new incremental run.

I cannot think of any cons of having this enabled.

Thanks!

yes i use it by default in all of my backup using VBR 4.1, no performance impacted.

Gostev; Is there anywhere one can read in more detail how the integrity check at hand (the one referred to in this thread) works, what it does?

... and are we warned by email (if e-mail notifications are enabled for the job) when an integrity fault occurs ?

Thanks in advance.

If for some reason the built-in check fails, it will be definitely reported in the job session and I’m pretty sure that this information will also appear in notification mail; though, need to double check it.

Thanks.
