rsync - Feb 2016 - Is there a parameter in rsync to clean $BACKUPDIR before writing to it (--backup-dir=$BACKUPDIR)?

Hi,

I am runing rsync --backup --backup-dir=$BACKUPDIR where the
BACKUPDIR=$(date +%d) to recycle the $BACKUPDIR in a month. But rsync does
not clean the  $BACKUPDIR before writing to it in cycling.

I guess you have to clean it manually before the rsync can write to it. As
my $BACKUPDIR is in remote machine, do you have to run ssh to delete it
first before calling rsync in a script? Or if there is better parameter in
rsync to automatically delete the old $BACKUPDIR, and create a new one?

Thank you.

Obviously you can ssh an rm -rf.  Alternatively, if you are in a
restricted environment where you are only allowed to use rsync you can
rsync --delete an empty directory to it.

Hi Kevin,

Thank you very much for the response. Actually, I don't think I need to
clean the backup dir defined in --backup-dir=<backup dir>, when the
contents has already been deleted in the destination (no exist), it will
delete from the backup dir as well in next cycle, correct?

Regards,
