I/O in VM when you backup (SQL tasks etc) is slowing down backup. Van: Gilberto Nunes [mailto:gilberto.nune...@gmail.com] Verzonden: woensdag 27 augustus 2014 18:55 Aan: Bart Lageweg | Bizway CC: pve-user@pve.proxmox.com Onderwerp: Re: [PVE-User] backup takes so long to finish
Hum... At first moment, I thought I/O could being a trouble, since I was ran backup in USB devices. But now, I ran backup task on SAS disk! So performance and I/O is not an issue here... And, I can't shrink the file, because the entire disk is being used to all databases as I described before... If somebody else has any other advice, I will appreciate...

This VM has a 300 GB disk size that was re-partition with 5 or 6 different parts, in order to allocate different databases... The issue is that the backup task takes 6 hours to generate a lzo file with 13 GB size! However, I have another VM, which is Windows 2008 with disk 120 GB size. The backup makes 74 GB file of size, and takes approximately 30 minutes!!! I can't see why the first task took so long time to finish!!! Can anybody assist me?? Thanks Gilberto Ferreira Gilberto Ferreira
