#918 multi-part backup Zip or RAR files

[Paul King]

Currently, administrators attempting to backup media along with other key files are generating zip files that may in fact be useless.

If the ISP has a size limitation on downloaded files, any zip backup larger than this is effectively inaccessible.

Worse, even when the size limit is exceeded, PGV allows administrator to download from backup page what seems like a normal zip file and reports no errors - it is only when user attempts (perhaps in an emergency!) to unzip the backup that they learn that downloaded zip file is corrupted

At least user gets an error message when downloading zip manually by FTP

Administrators should be able to specify a server file size limit, and the backup produced should automatically be broken down into multi-part archive to suit the limit

To this end, RAR should also be a supported archive format
