Error when Backing up Accounts by Remote FTP

[bgqs]

I have setup backups by ftp. All accounts are backing up correctly however, there is one which terminates before backing up all files.

Here is the error:

Notice this dir is a cache dir whose permission is CHMOD to 777. The cached php files are not 777.

Cpanel terminate during the backup and moves onto databases and mail etc.

How can I prevent this happenning ? The forum software is phpbb.

Thanks

You could either set that directory to be bypassed using this method:
cpbackup-exclude.conf format, missing something?
More on that here:
Backups cause processor usage to spike/perfomance to a crawl
And here:
cpbackup-exlude.conf

Or even better, move to SuPHP for added security which would prevent any files being owned by "nobody" in that cache, which would solve this problem all together for you.

Many thanks, suPHP here I come
