pleskbackup ftp tmp directory

[shalako]

I would like to run the following command:

/usr/local/psa/bin/pleskbackup -v --split=1G all ftp://<username>:<password>@<hostname>/pleskbackup

Problem is that when using the ftp output instead of a regular file output, the utility packages the backup in /tmp and this partition on our VPS is only 1GB.

I would like to know how to specify the temporary directory pleskbackup uses.

Thank you.
