9.1 Configure Auto Snapshot Setup in Proxmox VE

Automating the snapshot process ensures that your data is consistently protected without requiring manual intervention.

• For ZFS: Use the zfs command to schedule automatic snapshots. You can utilize cron jobs to automate this process. For example, to create daily snapshots of your ZFS dataset at midnight:

crontab -e

0 0 * * * /sbin/zfs snapshot poolname/datasetname@$(date +\%Y-\%m-\%d)

This cron job uses the zfs snapshot command to create a snapshot labeled with the current date.

• For Proxmox VE VMs and Containers: Proxmox VE has built-in support for scheduling snapshots via the GUI or CLI. In the web interface, navigate to the “Datacenter” → “Storage” → “Content” tab, select a VM, and use the “Snapshots” tab to manage and create scheduled snapshots.

9.2 Set Retention Policies for Snapshots

Without proper retention policies, snapshots can quickly consume storage space. Establishing and enforcing retention policies helps manage this space efficiently.

• For ZFS: Implement snapshot retention using a script that deletes snapshots older than a certain number of days. For instance, to keep 7 days of snapshots:

zfs list -H -o name -t snapshot | grep 'poolname/datasetname@' | while read snapshot; do
    creation=$(zfs get -H -o value creation "$snapshot")
    if [ $(date -d "$creation" +%s) -lt $(date -d '-7 days' +%s) ]; then
        zfs destroy "$snapshot"
    fi
done

Add this script to a cron job to automate the retention policy.

• For Proxmox VE: Utilize Proxmox’s built-in pruning options for VM snapshot retention. When configuring snapshot schedules in the GUI, you can specify the “Max Backups” to retain. Proxmox will automatically prune older snapshots beyond this limit.

Setting up and managing snapshot schedules and retention policies is crucial for data protection. It not only ensures that you have recent backups available for recovery but also helps in managing storage resources efficiently.
