Deduplication not working?

[medhahosting]

Does anyone else feel that deduplication on remote server (rsync via ssh) isn't working properly?

For example, I've got one cPanel server that's backing up locally to /backup and /backup is right around ~500GB but the same server's off-site (supposedly deduped) backup uses a full ~1TB.

I realize that checking utilization when deduplicating is different, but the 1TB drive this server is backing up to reports full and backups fail, so I presume it's using the full 1TB.

Does anyone else have similar happening? Any insight?

It certainly sounds like compression and/or deduplication wasn't correctly applied to the off-site backup.

I would personally recommend attic/borg, I've tried various remote backup solutions with support for deduplication and found borg to be the most effective in terms of speed and disk space usage. (Borg was forked from attic to continue development after attic's development ceased)

You can find borg/attic at:

I think this might be a bug with the new cPanel version, did you submit a ticket to cPanel support about it?

If yes then let us know the outcome.
