In my backup set, I have defined the backup retention as “Keep a specific number of backups: 200”. Now, the free space on the local backup filesystem is nearly 0 though the current number of kept backups is just 193. The next backup will likely run out of free space on the backup filesystem. So I could change the specific number of backups to be kept to 192.
BUT: Will duplicati free the oldest backup at the beginning of its next regular backup job? Or will it free the oldest backup at the end (in which case it could be too late)?
Additionally, is there a possibility to tell duplicati (GUI variant) to just delete the oldest backup and do nothing else, such that I can see in advance if there will be enough free space on the backup filesystem for the next regular backup job?
Thanks for your help,
