Error backing up RC3 forum

[Caesar]

I received the following errors when backing up my RC3 forum. Anyone have any clues? Btw, I'm using HostRocket as my host.

Make sure the directory you're trying to backup to has write permissions (CHMOD it 777).

Or backup via HostRocket's SSH, with this command:

mysqldump -uUSERNAME -pPASSWORD DATABASENAME > backup.sql
