How to Create Scheduled Snapshots in Google Cloud Platform
Yes, your server and data are on cloud, but to avoid the risk of unexpected data loss still you need to follow standard backup mechanisms provided by cloud providers like snapshots or replication. The best way is to take the disk snapshots – Operating System disk as well as data disks. And the best part is Scheduled Snapshots by which you don’t need to worry about regular snapshots. Here see a simple demo for scheduled snapshots in Google Cloud Platform.
Create Snapshot Schdule
First of all we need to create snapshot schedule and define when to take snapshots, where to keep it, how long you need to retain the snapshots etc.
Goto Computer Engine -> Snapshots -> Select Create Snapshot Shedules
Provide name and description for the schedule and also choose region if you want to keep it at some specific place.
Also choose the frequency as Hourly, Daily or Weekly and when to take the snapshot. In below example we have selected to take weekly backup on every Tuesday between 3 – 4 AM. Also set to delete snapshots older than 30 days.
Create the schedule and see details.
You can do the same via gcloud console or using API as well, refer GCP document for the same.
Attach Snapshot Schedule to a Disk
So we have a schedule created to take snapshot in specific intervals and now we need to select which disk we need to take snapshot of. Goto Disks tab and select the disk you want to attach the snapshot schedule.
You can see, the disk is used by myserver-101 (which is my VM) but no snapshot schedules attached.
Now, click on disk and you can see the disk details; then click on Edit button on top and attach snapshot schedule, and then Save.
That’s all, now you have your weekly automated snapshots mechanism which will take snapshot every Tuesday and will delete older snapshots automatically.
Since every snapshots will take some space on disk, please read GCP Pricing for Disks and Snapshots before you configure your snapshot schedules.
