Backups taking consideribly longer than before

Thread needs solution

Hi,

initially our backups (around 3TB) took 14 hours when doing a backup with verify and around 1 hour when doing backups without verify. The average backup size is around 10GB at most.

Now the backups take about 3 hours to complete. Average number/size of changes did not change. Any idea why this is taking longer?

Could it be that the backup archives are getting fragmented?

Is there any way to shrink/defrag the backup archives?

Hi ece,

The performance of backup into existing archive in 8th version of Acronis vmProtect depends on the number of recovery points which are already present in this archive due to deduplication feature which needs to perform scan through all preceding recovery points inside. In vmProtect 9 we have optimized this algorithm (internal bug ID is AVMPIX-1518) so that there is no performance dependancy on the number of recovery points, so you can check the behavior with vmProtect 9 Beta version. In vmProtect 8 the workaround is to disable deduplication feature in Backup Options->Additional Settings.

Thank you.

Thanks for the quick reply, Vasily.

Could you please explain in more detail...

Imagine: The original archive has been created 60 days ago, but the archive only keeps 10 restore points.

Does it mean that it is dependent on the original archive creation and the number of restore points which have been created since? Or really just the number of active and current restore points?

Hi ece,

There is no dependancy on the age of the archive. The only things that matters are: number of existing recovery points (most impact) and their sizes (less impact) inside the archive.

Thank you.
