Deleting .onbackup files
Currently my weekly .onbackup files take up some 10GB of drive space. Can I safely delete all but say the last 3?
It depends on risk appetite. Saving three version at a time is less risky than only one. If something goes wrong and you recognize the problem relatively late, your backup may have the issue copied already and might be no help. An older backup might not have the same issue.
I do a weekly backup and keep three weeks. Disk space is cheaper than the time spend to restore everything manually.2
I have in fact backed them all up on to an external drive.
Since my days of 40MB hard drives I have always had a thing about disc space usage!0
My first IBM-PC had 20 MB hard disk only. Time goes by.0
20 MB - luxury! The first university PC cluster my group was responsible for was in days when PCs didn't have any hard disks. We had to generate sets of 720Kb floppies that users needed to boot from, different floppies for different programs!
The new mainframe that was being installed when I first joined (1975) started with 1.25 Mbyte of RAM and 6 100 Mbyte disk drives with exchangeable disk packs.0
720 KB floppies? Luxury!
One of the first computers I worked with had a Williams Tube memory which was capable of storing 512 BITS of memory (Google it). That was circa 1962 though the computer was built 10 years before that.0
Is there a way to limit the amount of space for the backups? I have no issue keeping backups, just didn't want to manually delete every couple weeks. How many back ups are worth keeping? I currently have 14 weeks(36gb) on my machine. Is there any advantage in keeping backups longer? Moving them to a NAS? If you have to recover, are you only using one backup?0
The only way to manage the amount of space used by the backups is manually. Read Volker's comments above on on long/many of them to keep.0
