What provider are you currently with? Is it their web based backup tool failing? Do you have access to SSH on the machine?
I prefer to make all backups from the command line via SSH vs relying on a tool; you can see the commands on the
UBBWiki guide "
Backup Guide" (similar instructions are also available on the guide "
Migration Guide").
Additionally, the backup utility provided by UBB.threads has come a long way in more recent versions and could be utilized to jump to another provider if need be.
But it definitely think it's likely time for a new host if you're not getting any sort of timely responses to inquiries from your existing provider.
