right, press <Enter> *before* the command, *not after*. ***Never*** run
BackupPC_nightly from the command line. ***Never*** advise other to do so.
Really quite simple.
Before that, on 10/12/14 11:41, Stephen Mew had written:

Yes, it's a solution. The question remains, for what problem. If you know
*exactly* what you're doing, you can try that. Chances are, if you're asking
here how to delete backups, you *don't* know *exactly* what you're doing. If
you're recommending this, you probably also don't *exactly* know what you're
doing, otherwise you wouldn't recommend it. Removing one backup directory will
usually work quite well, if and only if no backups depend on it. Nothing will
prevent you from removing data still needed by other backups with 'rm'. Don't
expect BackupPC to handle the resultant pc directory gracefully.
If you want to remove *all* backups of one client (the original question
suggests this might be the case),
rm -rf /var/lib/BackupPC/pc/<client>
will work (supposing /var/lib/BackupPC is your TopDir ... mine is different).
No dependency problems, no summary files to patch. For removing single backups,
get Jeffrey's script.

nano? The only thing you need to know about nano is Ctrl-x. Tip for Debian
users:
update-alternative --set editor /usr/bin/nvi
update-alternative --set view /usr/bin/nview
But that's kind of off-topic (and a matter of opinion - I'm sure there are
other vi clones that are rather acceptable ;-).

If you want to get rid of all backups of one or more hosts, delete the host
directories (or move them to $TopDir/trash and BackupPC will do it for you).

That's correct. It's not part of the official BackupPC software, it's a user
contribution by Jeffrey J. Kosowsky. I don't have a recent copy, but I'm sure
Jeffrey does ;-).
Let me state this clearly:
After deleting backups, there is no *need* to initiate a BackupPC_nightly run.
BackupPC will automatically do that at some configured point within the next
24 hours. Only if you absolutely want to see the space freed as soon as
possible do you need to politely ask BackupPC to run the command as soon as it
is safe to do so:
# su backuppc -c "/usr/share/backuppc/bin/BackupPC_serverMesg
BackupPC_nightly run"
Hope that helps.
Regards,
Holger
