Great. Thanks for sharing that. The "~70GB/min" is quite amazing. Nice to know that. Absolutely there is still room for improvements. Let us know if you find the common factors that can improve the performance in general.

"apparent when choosing backup repo destination, can't read file system of file size on my disks. " -> Does that disk have a partition table? Please run the following commands in Clonezilla live command line prompt: sudo -i parted -s /dev/sdb print parted -s /dev/sdc print df -h cat /proc/partitions Please post the results of 2-5. Thanks.

Great. Thanks for confirming that.

No problem. Thanks for share that.

Not very sure what you meant. Could you please take a photo about the screen that you mentioned "When selecting directories"? Thanks.

Cool. Thanks for sharing that.

The priority is: /etc/ocs/ocs-live.conf (only exists for Clonezilla live, not Clonezilla SE) /etc/drbl/drbl-ocs.conf For live system, you can also assign the following in the boot parameter: extra_zstd_opt="-T0 -3" Change "-3" to what you want. However, normally it's not worthy since the time spent is much longer but the size does not reduce too much.

"But my main Core2Duo BTRFS box only works with third release back or older." -> What are the error messages if you use the latest Clonezilla live 3.3.3-15? Or maybe give testing Clonezilla live 3.3.3-16 a try? It comes with newer Linux kernel.
