scheduled backup failure
Just thought I'd report an odd occurrence. I have scheduled daily backups to two disks. I hadn't checked on them in a few weeks, but when I did, I found that one was working fine, and the other was not working at all. This second scheduled backup (to a new SSD) simply wasn't running. The "Last Copy" recorded for it was weeks ago, and the "Next Copy" was properly listed for tomorrow. The "Next Copy" was being updated every day, even though the copy was never made. The schedule seemed to be filled out correctly for daily operation, but I deleted and reentered it. It appears to now be working properly. Kind of strange. The lesson here is that if you have scheduled backups, check on the "Last Copy" occasionally to make sure they're really doing what they're supposed to be doing.

Did you have it set to not give an error when a volume was missing?

I can't be sure, but I don't think the volume was missing from SuperDuper. Certainly the volume was mounted on the machine, as the first clue I had that this was happening was when opened the volume to see what was not supposed to be there.
That being said, how do you set SuperDuper to give an error when the volume is missing? That would be smart thing to do. |

The default is to show an error (it's a checkbox in the settings sheet).
I'm guessing you had it unchecked and had modified the low-level ID of the volume that wasn't running, so while the name may have been the same, it was no longer the same ID as it was before.

Ah, I see that checkbox, and it was not checked. Maybe I accidentally unchecked it? The disk at issue is a new SSD, and I'm writing to two partitions on it. A "weekly" partition, and a "daily" partition. It was the latter that wasn't working. The former was. Both partitions were created at the same time, so it isn't clear why one low-level ID would be screwed up and the other wasn't.

I don't know, Dan. The evidence is, at this point, lost, so we'll have to see if it happens again.
Remember, we support notifications, and you can use those to see if the backups are running...

I thought I'd add this to an old query. I have a couple of daily scheduled backups. It seems they've been failing to run for a couple of days. Turns out that happened when I upgraded from Monterey to Sonoma. I don't think my cron file was erased, as I have other stuff in there that continued to work. I should have looked at it. But I just erased the SuperDuper schedules, reestablished them, and now scheduled backups again work perfectly. Is there something about OS upgrade that messes with SuperDuper cron schedules?

There shouldn't be; I haven't seen cron entries go away during an OS update. Perhaps the agent wasn't running for some reason?
(Remember - the cron entries are there for "backward compatibility" - they indicate when the backups run, but aren't actually running them: the actual backup is run by our LaunchAgents.)

Well, it is a little funny that my scheduled backups were working for a year, and then quite suddenly, when I upgraded the OS, they stopped happening. Under scheduled copies, SuperDuper accurately admitted that they hadn't been happening, though the backups were still formally scheduled. I take it this isn't happening to anyone else? I should say that I hadn't even manually launched SuperDuper for a few months, so it isn't as if I changed something in the app. Oh well.

I'm not saying it's not "odd", just that it's not "typical". Since you "fixed" it, though, it's impossible to diagnose after the fact.
Next time, if it happens, send me support email and we'll work through it and try to figure out what it is.
