Slow Backups

Nov 14, 2013 at 4:06 AM
Hi,

I've recently tried HVBackup - I find it better and easier to use than the others I've tried but I have one question.

Is there any way to make the backups run faster. I have a 800GB VM which takes almost 12 hours to complete whereas with other systems takes around 2 hours.

I'm sure I'm missing something.

This is a known problem. The ZIP library used has bugs when using multiple cpu cores. So it was limited to using only one core. There were threads about using a different compression engine. But I'm not sure if someone is working on this.

Any thought to switching over to 7zip?

Turning off compression completely is the easiest fix. On a 148GB VM it cut my backup time from 200 minutes to 21 minutes. Add the flag "--compressionlevel 0" to the command line.
