When I worked for a telco in the 80s they had a nightly script for two backups over three tapes. The script asked the operators first for tape 1 then tape 2. Started the second backup which asked for tape 1 again. This overwrote the first backup. Tape 3 was never used. I found that problem before they ever needed a restore.
