What backup files are safe to delete?
Our environment is set to run backups to disk, and then to backup that data to tape so the disk space can be cleared out for further backups.
Our tape drive died so the data hasn't been being backed up to tape, and now our storage array is full.
What I'd like to know is what files are safe to delete from the location we use to backup data to? There are a number of .bkf files, some as old as October, most recent - can the "old" ones be safely deleted?
There are also a few "IMG######" folders with a number of files inside of them as well - are they safe to delete?
I need to clear up some space, but I don't want to delete something that could prevent future potential restores from working, or something that would prevent the existing disk backups from saving correctly.
