I read about the most convoluted ways to back up SBC systems…. some back up only data, some use arcane commands to do the job – few if any are a single click job for a complete backup that can even handle larger or smaller SDs.
Except for Raspberry Pi SD Backup.
I don’t know how many of you are familiar with this but I have a number of Raspberry Pi 2 and 3 units and as well as liking to keep regular backups, I like to have snapshots before I try something new – one of my main machines is in Spain, currently a long way away and the other is in the house, away from my office.
In Raspbian from the GUI you simply go to accessories, SD card backup and press a button to back everything up to an SD card that has enough room to store everything. This card can be put in another Pi and will run – every single time I’ve done this it has worked with no data loss even though the Pis are actually running as I’m backing things up.
So two things for any budding wizards out there…
1. I cannot find a way to schedule this from the command line – it seems it only runs in the GUI
2. Why can’t other systems do this – for example Armbian? Now, The so called Raspbian for the Orange Pi has the same feature but it DOES NOT WORK – I doubt anyone uses their software anyway because Armbian is better by some way… but really – simple backups means more experimenting means greater innovation, fewer heart attacks. PLEASE someone tell me I’ve missed something that does the job (and please don’t mention DD and other convoluted data only or multi-part solutions – I’m talking about a single command that makes a duplicate SD even if it is larger or smaller – that works without issue…
If Raspberry Pi people can do it – why can’t others, I wonder?
