Restore from tibx file!

Thread needs solution

From much reading here in the forum, as well as several KB files and the user guide, I understand that all tibx files created by a ATI 2020 task are interdependent and any one of them being corrupt or deleted makes the whole string unusable. I suddenly today had the thought that my backup procedures may be flawed and unusable, although they complete successfully without error.

All my tasks are non-scheduled, run only full backups, “keep no more than 3 recent versions”! They are started manually when needed (after new installs, software updates, data changes, etc) and all run attended after hours via a batch file.

The source of my concern was noticing the list of tibx files in a target drive:

FileName.tibx

FileName-0009.tibx

FileName-0010.tibx

FileName-0011.tibx

I feel sure there must by more going on here than I understand yet! Are files FileName-0001 thru 0008 actually deleted, but not making the backup unuseable? If I need to restore from this backup, do I select the newest tibx file, or the un-numbered file?

I have needed to do a restore a number of times in the past, but with tib files, without these concerns.

Thanks for any comments…. Robert

It's OK for ATI to delete the files.  That's what its automatic cleanup does.  Those 009, 010, and 011 are the "no more than 3 recent versions" you told ATI to keep.  All information it needs about the earlier versions is kept in the unnumbered file.

In doing a recovery you would pick whichever backup you want to recover from.  (You might not want the most recent backup for whatever reason.)  I'm not sure what happens if you pick the unnumbered file.  It will probably use the most recent backup.
