| - | :!: You can back up all the VM's, XenServer hosts, and metadata for a XenServer pool from a single XenServer host. | ||
| - | |||
| - | :!: Consider this a disaster recovery backup. | ||
| - | |||
| - | :!: Here we use an NFS mount for backup storage. | ||
| - | |||
| - | :!: XVA backups are compressed on the fly. | ||

| - | ===== Prepare the NFS Mount and Test a Manual Backup ===== | ||
| - | |||
| - | :!: Choose one of your XenServers to be the backup server, generally the pool master. | ||
| - | |||
| - | :!: Here we assume you have a shared NFS folder ''/ | ||

| - | # Mount the backup share | ||
| - | 10.10.1.9:/ | ||
| - | </ | ||
| - | |||
| - | Mount the share, check it's mounted and test a manual backup: | ||

| - | unzip XenServerBackup.zip | ||
| - | rm -rf __MACOSX/ | ||

| - | |||
| - | :!: You might want to use IP addresses to control which network interfaces are used for the backups. | ||
| - | |||
| - | Change the names and filenames to the names you have for your XenServers according to the article: | ||
| - | |||
| - | < | ||
| - | cd /opt/backup | ||
| - | |||
| - | vi audit.sh | ||
| - | |||
