Not a bug, Just a feature request on merging delta files.

Hi, I'm back again.
I'm playing delta file in recent days, I think if we can have a way to specify multiple -D in order when we --apply-delta.
This way, we can apply multiple delta files in a single command line,
Within blocksync-fast, it internally merge all delta operations, So we can prevent some duplicate write operations to target devices.

Thanks.

Hello,

Thank you for your interest and contribution to the development of the program.
Your request is a great idea – optimizing the process to start with the latest delta files and skip already restored blocks makes a lot of sense.

The delta file headers contain additional information, such as their creation time, which could be useful for this optimization.
I plan to implement this change in the next program update.

PS. I hope using blocksync-fast has been helpful for you!

blocksync-fast helps me a lot.
I use it on my home network, Before, when I do dd on the storage disk image,
even with 'ionice -c 3 dd', system will still get hang.
blocksync-fast almost eliminate this.

Thanks
