I've read through posts on this board regarding removing old .tib files so your HD doesn't fill up. I run a differential backup every night, but suppose I only want to keep the last few days worth of backups or my external HD will get close to filling up. I have created a batch file to remove all but the first backup (ie. the full backup file) and the last 3 backup files. Suppose I have backup.tib, backup2.tib, backup3.tib, backup4.tib, backup5.tib. Tonight's backup runs, the pre-command runs and removes the oldest backup while preserving the original full backup. ie. "backup2.tib" is deleted. Now the backup runs, ATI automatically names it backup2.tib since this is the first numerical filename available. It means that now my backups aren't in alphabetical order, but I can always order them my date created in explorer, so no probs. So. All great. Except if I want to restore from a backup - by opening any of the differential backups I am presented with the list of original date/times to choose from in ATI. Although backup2.tib is my newest backup, ATI tells me it's timestamp is still the same as the ORIGINAL backup2.tib - the one that was deleted. If I restored from backup2, can I expect any problems? Is there a tidier way of doing this, or making Acronis report the new timestamp for backup2?
