I'm upgrading from a Inland 256GB M.2 PCIe NVMe SSD to a HP EX900 NVMe PCIe M.2 500GB. In the past I've used Clonezilla to save an image on old drives as backup but this time it's struggling.
I booted Clonezilla from a USB and selected the disk-disk option like normal. It started out decently well at ~60 gigs/min but only made it to 10% before dropping to 600 mb/min. It's now been running for 8 hours and has '>65 hours left'. How on earth does it take so long for two drives with over 1gbs read/write speeds, connected on the same mobo to clone across a 16 core cpu? I didn't think this poor performance could be a reality.
I know there's nothing wrong with the drives as I used them both minutes before starting the clone. The 256 drive has ubuntu18 and the 500 drive did have win10. The Clonezilla stable version was downloaded only a few months ago.
What are the better options for cloning drives? Or where did I go so horribly wrong with my approach? Would going nvme -> image on old HDD -> new nvme be magically faster?
I'm looking for something that preferably:
only copies sectors with written data (Clonezilla was making images of the entire drive when <50gb had been used)
also copies the bootloader/grub (I'd prefer to skip mucking with this if possible)
performs at speeds compliant with 2010's tech instead of 1990's
Thanks for the suggestions!
