Partclone

The best cloning/imaging program! You can use it from CLI or through default Clonezilla, but it's definitively my preferred software. It saved my bacon many times! For damaged disks you can use the "rescue option" (-R or --rescue), even if sometimes I had to switch to ddrescue for data recovery on failing hard drives. If you want the most recent version of Partclone, I suggest to use the Clonezilla Alternative Live CD. I hope I can see a new stable version, even if the 3.11 is OK (I never had issues, despite its "unstable" state).

Documentation needs a little work. While many of the programs generated during a build is fairly well documented, some of the documentation overlaps and is rather confusing. For example, If using partclone.dd your arguments don't need to include the -c or -r arguments if cloning or restoring respectively. partclone.restore is supposed to work with partclone.dd files, but it doesn't work right. That said, if you use partclone.imager to clone unknown filesystems, things will work. Other than that, very useful program. Relatively easy to modify and add elements if needed for customization.

I have used Partclone to successfully back up and restore EXT4 partitions on a MicroSD card. (In case you're wondering why someone would do that to a MicroSD card: the partitions contained OpenWRT pivot overlays for routers.) Partclone works great for the purpose and is easy to use.

good job

I use it in an offline backup solution for stand-alone systems. It works great.
