Hi,
I would like to check if there is a possibility to merge snapshots in the same repository? I am having some curious effects using “forget” because it recognises different patterns (so to speak)
My scenario is as follows:
-
Initial backups was done individually on a folder by folder basis with the assumption that I could have a few folders fully backed up before proceeding with the next within the time I have available without running an entire backup and wait for the process to complete.
-
Subsequent backups where done by selecting all backup sources at once once I found that it is easier to browse through the files using FUSE. This would also mean that the backups would deduplicate files and folders already backed up hence not drastically increasing my repo size.
-
All was good in the backup front, however when I want to prune things work differently from what I assumed it would be. The forget policy keeps taking each so called source signature as an individual backup. As in, if I say delete all snapshots in the last 30 days or keep-last 30 it lists the last 30 snapshots that belong to each source signature/pattern.
E.g. Day 1 I backed up D:\Work_Folder, Day 2 I backed up My Documents folder, Day 5 I backed up both D:\Work_Folder & My Documents folder, this is taken as 3 different signatures. So if I continue to backup D:\Work_Folder & My Documents for 40 days and then set a forget keep-within 0y1m flag I assumed that last 30 days of snapshots in my repo will be preserved deleting older ones. However, what happens is that backups done on Day 1 and Day 2 are preserved supposedly they meet the criteria even though they where done 40 days ago and the backups done with the pattern done on Day 5 works as expected with those older than 30 days being removed.
I would assume that since I backed up from the same sources using the same machine the subsequent backups should have indexed the files and folders in the latest snapshot, so why does the forget policy not apply for the entire repo instead only applies for a particular pattern?
Please find the output from the dry run below:
PS C:\Users\User> restic -r W:\restic\ forget --keep-within 0y1m --prune --dry-run
