This trick, was thought to me by some canadian guys in Calgary, We backuped not only to Tapes or Magneto Optical drives, bt to laptops. We used to develop SCADA systems using Unix ( IBM, ALPHA, SUN ), and we used extensively Telnet do remote control and FTP for file transfer.
This systems may have a couple of realtime servers, other 2 historical database servers and an engineering station, all of them UNIX, but we started using cheaper laptop PCs for the administration and engineering. funny thing is I started used ortodox file managers in CMS, then used them in DOS, QNX, Windows, I love the modern ones like Total Commander that can do FTP, edit even connect themselves to cloud storage. We ussually added SAMBA for direct connexction to the servers, and any kind of printer bridge, to print unix reports in regular windows printers.
We also made all user's directories backup, and zip, so you can find with total commander any filename or content, in directories or zipped files, at different checkpoints, and compare 2 files contents. For me is easier to use and less error prone, than versioning systems, specially whan you have engineering projects, comprising drawings, documents, email, firmware, even accounting spreadsheets, all in the same project directory
