I'm trying to get my Mint desktop computer's home directory and my Debian media server's movies/shows directoiries backed up. When this is all said and done I'll be backing everything up to a 5 TB external USB HDD with it's own powers source connected to a Raspberry Pi 2 stored away from my house via colocation. But I'd like to get the many TBs of data I have copied before I move the PI2 + HDD off site. I've been reading here -> http://backuppc.sourceforge.net/BackupPC-4.0.0alpha3_doc.html#BackupPC-Introduction on setting up backuppc but my head is starting to hurt. When I read over that material it sounds like they are expecting the destination of my data to be the server that's running backuppc but that's not how I'd like to run this. I want my backups to be initiated from my in house desktop and media server (the sources) using backuppc, to the RP2+HDD (destination). Is this possible?
Also, before I move the RP2 off site what would be the best means of using backuppc to copy my data locally? Can I setup backuppc to copy from my desktop and server to the HDD via the USB connection and then change the backuppc configuration after moving the PI2 off site or am I doing to need to do this over my home network via the RP2's ethernet port? If anyone has any suggestions and or corrections please give me a hand, I've never used backuppc and I have no idea what I'm doing? Thanks.
