@ -283,3 +283,19 @@ Preparing the backup server
Extra options needed for proxmox with HA:
* --no-holds: To allow proxmox to destroy our snapshots if a VM migrates to another node.
* --ignore-replicated: To ignore the replicated filesystems of proxmox on the receiving nodes. (only backup from the node where the VM is active)
I use the following backup script on the backup server:
```
for H in h4 h5 h6; do
echo "################################### DATA $H"
#backup data filesystems to a common place
./zfs_autobackup --ssh-source root@$H data_smartos03 zones/backup/zfsbackups/pxe1_data --clear-refreservation --clear-mountpoint --ignore-transfer-errors --strip-path 2 --verbose --resume --ignore-replicated --no-holds $@
zabbix-job-status backup_$H""_data_smartos03 daily $? >/dev/null 2>/dev/null
echo "################################### RPOOL $H"
#backup rpool to own place
./zfs_autobackup --ssh-source root@$H $H""_smartos03 zones/backup/zfsbackups/$H --verbose --clear-refreservation --clear-mountpoint --resume --ignore-transfer-errors $@
zabbix-job-status backup_$H""_smartos03 daily $? >/dev/null 2>/dev/null
done
