I would like to make manual backups of an SD card as a disk image so that it can be easily recreated when needed. I’d like to keep a few versions in case there is a problem I didn’t know about, it can be rolled back.
How can I do this incrementally, or with de-duplication, so that I don’t have to keep full copies of the complete SD card? It’s very big but most of the content won’t be changing much.
It’s for MiyooCFW ROM which is on FAT 32-formatted micro SD card.
Thanks for your help! Also let me know if I am going about the problem in a wrong way.
note to myself and anyone with same problem who finds the thread:
stumbled on
psync: A naive tool for syncing partitions using rsync which sounds like it’s at lest trying to do this task.No documentation, no users, no project changes in 6 years… Will give it a try another time.
