Thanks for posting this, I'm also having this issue (server crashes —kind of— at backup time with an unhandled ArrayOutOfBoundsException) and your solution seems promising (and kind of obvious in hindsight since I knew it had to be something with the backup). I'll try it next time I restart my server (which could be the next time it crashes at this rate).

edit: success!

From issue https://github.com/CreeperHost/FTB-Backups-2/issues/38 this has been fixed in FTBBackup v1.0.17. After updating, I haven't experienced this crash in the past 16 hours on a FTB Inferno server I setup for friends.
