Created February 6, 2024 07:12 — forked from cabal95/vm-backup.sh
I use this script to backup my QEMU/KVM/libVirt virtual machines. The script requires KVM 2.1+ since it uses the live blockcommit mode. This means the data in the snapshot disk is rolled back into the original instead of the other way around. Script does NOT handle spaces in paths.

BACKUPDEST="$1"
DOMAIN="$2"
MAXBACKUPS="$3"
if [ -z "$BACKUPDEST" -o -z "$DOMAIN" ]; then
echo "Usage: ./vm-backup <backup-folder> <domain> [max-backups]"

                Rsync over SSH - (40MB/s over 1GB NICs)
              
          

        

      

        

  

      

    
The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)


This creates an archive that does the following:


rsync
(Everyone seems to like -z, but it is much slower for me)


    

  • a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
    • 

  • H: preserves hard-links
    • 

  • A: preserves ACLs
