Re: [ovirt-users] Backups take sooo long, how can I improve the situation, where is the bottleneck?

Hi Florian, Did you check the IO load on the SPM host during the backup? If you have 1Gbit network then the maximum theoretical IO is restricted to 100MB/s . So if you get 20GB raw preallocated disk then a single disk backup will be about: 20/0.08/3600 hours x 3times~10mins: .08 is 20%

Hi Charles, How are you folks doing your hypervisor level backups? Under ESXi I used GhettoVCB which basically took a snap shot, copied the disk image to another location, then deleted the snap. Thank you for this hint, I didn't know about GhettoVCB and I'm definately going to have a look

Re: [Users] backups

The work-around for this is to SSH into the guest first, put the database into backup mode(maybe run sync a time or two to flush out as much from RAM as possible), take the snap shot, ssh back in to resume the database, backup the snap, delete the snap. The main problem in oVirt with this
