lack of error handling within backup manager

[l33m4n]

there is simply a lack of error handling within the backup manager. if all files do not contain the correct time format, it will fail to load all backups.

This can be replicated by taking a backup and removing any part of the "20241015_00000142" part of the file name. To be fair this is a self inflicted bug. This should not occur doing normal use case, however it would be best practice to add some type of error handling. I would like to add this at some point if i can find the time.
