This should be easy but ...
I have been working on a Google Compute Engine persistent disk image that I'm calling utilserver
, and basically now need to build it again from scratch, but I might need the original one to try a few things in case problems come up. So I'd like to rename utilserver
to utilserver-backup
and then create a new utilserver
that will hopefully end up being more correct. However, under the web console for my project there's only a "Delete" button, no "Rename" button. Neither does gcutil
seem to have a rename command. Ok, I tried creating a snapshot of utilserver
and then from that a new persistent disk called utilserver-backup
, but when I did that the new disk looked like a completely new image--none of my prior installation work was on there. Any ideas here?
You can create a snapshot of your disk and then can create multiple disk from that snapshot. By creating the snapshot you will have the backup of your original disk. You can then delete the original disk and create a new one with the same name. You can refer to the following link for more details about snapshot: https://cloud.google.com/compute/docs/disks/create-snapshots
I personally have tried creating a new disk from snapshot using the following command and it created a new disk with all my data
gcutil adddisk <disk-name> --project=<project-id> --source_snapshot=<snapshot-name>
