It would be a great addition to UrBackup if the Archiving function had options to setup a different location/folder for Archived backups and the ability to automatically compress and copy the compressed data to said different location/folder at scheduled time of Archiving.
there is an older thread Feature Request - External archiving
The first step to get this feature would be that the command tool is able to list all backups that sign as archive.
Than we need a merge an export tool for backups
and than a import tool for recovery
In my opinion the support of an external archive would lift urbackup into the upper class of backup programs.
