Let’s say i made 10 snapshots on top of the base.

Now can i delete snap no. 5? Will the snaps after 5 will be affected?

Solved

Yes, one can delete consecutive snapshots. The data won’t be deleted unless all snaps ( reference points ) get deleted.

Note: If you delete the original file and delete all the snapshots made when the file is still there, the file will get deleted permanently.

    You missed an important part of that quote:

    Send/receive of subvolume changes, efficient incremental filesystem mirroring and backup

    This is explicitly talking about a different feature that can incrementally sending changes to the filesystem to another filesystem as a backup. Not at all about how snapshots work.

      Hmm, yeah, I guess I’m wrong there.

      My interpretation was that since send/receive foots on snapshots, those would be related, but I guess, the incremental backup is actually a separate thing.
      Some articles online call them “incremental snapshots” as well, which is where I might’ve gotten that initially, but I agree that on a logical level, they’re not that, even if they’re similarly space-saving.
