I activated backup for my Linode and ran a backup and now want to restore. However the restore process said I need to allocate disk space by doubling my current disk space. Can someone explain why this is necessary?

Once the restore is completed, can a go back and reduce my storage to what it was before?

Thanks!

Answering my own questions....
Looks like a restore doesn't actually overwrite an existing disk image, but creates a new image altogether which co-exists next to the image that you actually want to replace. You can delete the old image and de-allocate the extra space again.

If this is not the case, please advise. Thanks. --- L

That is indeed the case!
