NAS with File Versioning + multimedia server

NAS for shared backup. Looking to replace a pair of Windows machines being used as NAS storage. Each machine is network storage for local machines on their respective LAN. Each server also uses CrashPlan to back up their files to the other server across the country. One of the servers is also acting as a PLEX media server.

Wish list for new devices:
– File Versioning – ability to roll back to multiple versions of files
– App for organizing photos (seem to have a lot of photos duplicated across multiple computers)
– Would prefer a pretty standard power supply if possible, internal if not too expensive

Our current data set is in the 300GB range with about 200GB synced between servers.

You definitely need a Synology with its amazing file version control. And you need plus series with btrfs for folder snapshots. So you can not only see previous file versions but also entire folders. An internal power supply will mean DS1517+ or DS1618+, but this might be a little overkill for 200GB storage. The 2 bay option like DS718+ (or ds218+ as a budget option) will ensure you get an amazing multimedia center and incredible photo manager with things like geolocation and even face and object recognition. All this is done automatically in the background. A power supply will be external but pretty small. Alternative for CrashPlan could be BlackBaze with unlimited storage space. Or simply use two Synology to automatically syncronize all data between two remote locations.

For backing up your NAS do consider BackBlaze. You can try it for 15 days free if you don't believe its good. But the main reason is unlimited backup size. Everyone else like Dropbox, Amazon, and others charge per gigabyte. But  with this one there is no price difference either you backup 2 bay or 8 bay NAS. The other great feature is version control. So even if you get hit by ransomware type of virus or simply deleted or mistakenly changed few files. You can restore your data from historical backup versions and get all data back.
