fsarchiver taking ages to backup and restore
Using Linux Mint 19.1 bootable USB
Ext4 filesystem
Processor 8600k
Ram 16gb
By default fsarchiver uses zstd compression
Earlier when I used the following two commands, each command individually took maximum 5 minutes to complete.
fsarchiver -v -j6 savefs /backup/backup-fsa/backup01.fsa /dev/sda2
fsarchiver -v -j6 restfs /backup/backup-fsa/backup01.fsa id=0,dest=/dev/sda2
Now, each command takes couple of hours to complete. I noticed that mainly one core and 20% of my ram is used during the process.
Update 1:
Just to make sure, dd works fine. It makes the image fast. So, I do not think there is a hardware bottleneck. I think I am doing something wrong with the command.

Since neither RAM nor CPU are bottomed out the culprit could be related to
- having much more data (so that more stuff has to be copied),
- the disks themselves (being nearly full or using the same bus for reads and writes after moving hardware around), or
- the connection to /backup (if it's a remote filesystem or an external disk accidentally connected to a USB 2 port).

Is there a possibility that there is a bug in fsarchiver? Or, are there any params using which I can speed up the process?

Sure, have a look in the fsarchiver bug tracker,man fsarchiverorfsarchiver --help. I've not even heard of this tool before.
