Hi,


Maybe over those 50+ days the backup's preliminary checks of the slowly growing AC database (and possibly the separate hideous imported items folder) are taking longer and longer?

That is, maybe the AC backup program is still starting exactly on time, but it might be taking longer and longer to reach the point where it gets around to creating the actual backup file and uses this delayed creation-time the file-name.

Windows defaults to just hh:mm displays, but you can see the modified/created/accessed times in hh:mm:ss with the free nirsoft bulkfilechanger.exe.

You can get the current nirsoft utilities zip file, whose password is nirsoft9876$ (to avoid pesky false positives from anti-virus programs) from www.majorgeeks:

Or you can wrestle with wmic to get hh:mm:ss data:

In any case, the time when the backup finishes after your specified 12:00 start time may be what really matters. With AC, backups should take longer and longer to finish as data (and maybe imported items) are added.

Cheers,

Carl Fogel
