tl,dr How do I filter snapshots that are identical to their parent from
restic snapshots, or how do I prevent restic from making snapshots if they would be identical to the parent?
I have a folder that does not change most of the time, except for sporadic bursts of activity once or twice a week. When it is changing, I want it backed up frequently.
So far my strategy has been to automatically back it up hourly no matter if it changed or not, and restic has had my back space-wise and speed-wise, but it does mean my snapshots list is full of snapshots that are identical save for their date. I worry that
when something happens and I need to restore something without knowing exactly when was the last good copy, finding which snapshots are worth looking at will be a pain. if
So, is there a way I can filter out dupes when listing snapshots? Abort a backup if it would be a dupe? Clean up dupes after the fact? Something else?
