Tardis 1.0.2

A com­mand-line light­weight backup server

Linux User & Developer - - Reviews -

Tardis pitches it­self as a free al­ter­na­tive to ap­ple’s Time Ma­chine backup app. How­ever these sim­i­lar­i­ties re­fer to fea­tures only rather than the in­ter­face. In­ter­ac­tions with Tardis, un­like the swishly graph­i­cal Time Ma­chine, take place via the com­mand line. This isn’t a crit­i­cism, rather just a heads-up to those who might be mis­led by the de­scrip­tion on the web­site.

Be­yond ap­pear­ances, how­ever, Tardis does ex­actly what it prom­ises. It takes in­cre­men­tal back­ups and has sim­ple CLI util­i­ties to check, com­pare and re­cover from the backed-up files. The tool runs in a client-server mode, and the server is light enough to be able to run on the older Rasp­berry Pi 2. You can also choose to run both server and client on the same com­puter, which is the most likely in­stal­la­tion for use on a sin­gle ma­chine.

Tardis is writ­ten in Python and the in­stal­la­tion as de­scribed in its GitHub page is straight­for­ward. The server is con­trolled via a sin­gle con­fig file and the in­stal­la­tion comes with a tem­plate to get you started. The only real set­ting you have to edit is the lo­ca­tion of the back­ups be­fore you start the server. You’ll also have to cre­ate a user named tardis.

When you call on the server from the client on a re­mote ma­chine, you can add a pass­word to en­crypt the back­ups. Every­time you run the tool it’ll cre­ate a new time-stamped backup set. Re­cov­er­ing the data from the backup set is also fairly sim­ple. Al­ter­na­tively, you can mount the dataset as a com­plete file sys­tem.
