#StackBounty: #partitioning #backup #dd #ddrescue Copying raw partition sequentially, in chunks, with error recovery

Bounty: 50

Normally if I want to copy a raw partition /dev/sdaX (with i/o errors when reading), I would just go with ddrescue <src> <dst>.

The case here is that I’d like to be able to copy this partition in smaller chunks (e.g. 1GB partition in 10*100MB chunks), but not all at once, and glue them together afterwards. Imagine this as a scenario where you want to copy that 1GB partition from PC_A to PC_B but you only have a 100MB usb stick available.

Is this technically possible? Would ddrescue be able to do that, if so, how?
