It should be great if in JoomlaPack Remote could be a field to write the description.
When you make backups from JoomlaPack Remote on the "Administrer Backups Files" section of JoomlaPack(online) appears the common description:
XMLRPC backup
..generally when I administrate the backups I don't see the names of the files but the name of the description...because I use this syntax:
WEBSITE NAME - DATE(in the European format DD-MM-YY) - HOUR
I hope this can help!
thanks,
