>Alternatively is anyone aware of a similar device (mostly closed box, rechargable internal battery, wireless accessible) that either has internal SSD storage or into which an SD card can be installed that also has a *nix filesystem underneath? I am not sure to understand the rechargeable battery requirement. I mean, the thingy needs to be connected to mains anyway to recharge the battery and - before or later - it will happen to exhaust the battery mid-backup. Personally I would either get a "normal" UPS (that stays always in the office) and connect to it any of the "common" mini-pc's, sometimes called "brick pc's", like (example only) the Ibtel NUC's: https://www.intel.com/content/www/us/en/products/boards-kits/nuc.html https://www.intel.com/content/www/us/en/products/boards-kits... But really, why do you want to carry with you BOTH the data AND the hardware? Once upon a time those kinds of backups were made using ZIP disk, there was a "backup" machine on the network with a ZIP drive and what was carried home at night was just the ZIP disk (at the time the policy was "integral" backup every two days and there were three disks, labeled "Monday", "Wednesday" and "Friday" - and yes, all the non-replaceable data did fit into 100 MB). Nowadays all you need is either a USB disk in a case or a "cartridge like" disk, example: https://www.addonics.com/category/removable_drive_system.php https://www.addonics.com/category/removable_drive_system.php
