How to reduce snapshot size

I am doing snapshots recently to backup my data. But their size is growing. Even when i do the cleanup, the snapshot size remains the same as it was before. Few days ago because of my fault, my script filled all avaliable 20 gb space, i deleted al those files, so i have 7 gb free now but myand so snapshots are now 20 gb sized (and their creation time is 20 minutes!).

I think the snapshot size may be growing because of ‘rm -rf’ may only mark data as ‘deleted’ but do not ‘annulate’ disk space and DO snapshot burner copies that as well. IDK how linux file deletion happens, correct me if i’m wrong.

I think the easiest way to fix it is to create new droplet and copy everything to it. But please help if you encounted that problem and know a better way to fixed.

Ok, so I spoke to the support team and found out that although you’re not using the “empty” space on the droplet it gets snapshotted as well. The file size is not compressed. So if you’re running a 20 gb droplet, the unused space gets added to the snapshot. I think it’s better to switch to alternative backup methods. You don’t want to end up with more than a dozen snapshots weighting at 19 gb’s each in the end.

I’m having the same issue. My latest snapshot is huge compared to the one just created a couple of days ago. 18.14 GB vs 2.65 GB. I’m running a basic LEMP setup with WordPress. Looking at my “/” directory as root with du -sh / it’s only showing 2.1G. Where are all these huge files?

Are you sure you’re not just using that space even though you deleted the files? Files that are still being used by programs will stick around when deleted until those programs stop using them. They contribute to filesystem size that way.
