Backup failing on large website

[mashamit]

Good Evening,

I have a several domains on my plesk account, most of whic hare under one subscription which all backup without issue.

I have 1 domain on separate subscription which is 4.8gb in size (due to video files). Everytime I try to back it up internally or to an external FTP site it fails and the /usr partition becomes full.

Any help to resolve this issue would be greatly appreciated

Extra Info

I managed to get a backup made last night, which seemed to work (no error at plesk side). I tried to download directly from the backup location to my desktop and the file failed as corrupt. I also tried to recover to plesk, but the /tmp location reported being full then I lost access to plesk until I purged the /tmp folder via SSH.
