I have a question about restic “forget”.
I’ve set up a cronjob such that restic backs up my dropbox, some local folders, and an external hard drive (if it’s present). The snapshot is pushed to an s3 bucket.
Due to a lack of available ports my external hard drive is not always plugged in. Some snapshots will therefore not include the external HDD.
When the backup completes I run
restic forget --keep-daily 7 --keep-weekly 4 --keep-monthly 12 --keep-yearly 7
Am I right in my assumption that restic forget could pick all the snapshots that don’t have the HDD? Is there a more appropriate approach for this situation?
