I found out why VictoryBattles is taking forever. Just about an hour ago, I discovered MySQL was down and wouldn't start. The hard drive filled up again. You must have entered the command in such a way that symbolic links were dereferenced and converted into the actual files, as there were literally 41 recursive copies of every single file of VictoryBattles, which amounts to perhaps a million files. (Did you use -L?) Freeze, next time, please don't store your backups in a public location either.
I just finished wiping 39 of these copies, keeping the first copy and one recursive copy for good measure. A total of 134 GB was deleted.
