Hi, I only got my Jetson nano yesterday so please excuse my complete naivety with this platform.
And I am barely literate with Linux although I have been playing with Raspberry Pi for a year or so.
The Jetson will be a hobby AI/deep learning exploration machine. As such I expect to stuff it up a lot.
I just want to be able to backup the machine so that when I stuff it up I can fall back and try something else - this means the set of software I need cannot be determined in advance
For the Pi I could take out the sd-card and use my windows machine with Win32DiskImager to read the image to the local hard disk.
That way you end up with a series of fall back points any of which can be written back to the card if needed (also using Win32DiskImager).
- I only have one linux based machine - the Jetson
- it only has one sd-card slot
I have searched these forums and there appear to be several themes
- use ‘dd’. In the end I dont think this is relevant as it is the active file system that I am trying to backup. And even if it could backup it up how could it restore it?
- Use ‘disks’. This just refuses to work on the active system as it cant unmount it - fair enough.
- Use Etcher (windows). This might work except it can only clone an SD drive to another SD drive so I will end up having to buy and manage a series of tiny cards.
- spend a whole lot of effort to learn how to create custom images - this kind of defeats the fallback backup idea.
I also tried Win32DiskImager but it cant understand the card format.
Am I just asking the wrong question or are there really no system backup tools ?
