Acronis for Mac - very poor performance
It looks like Acronis doesn't properly utilize all resources available in the system.
142GB Backup took about 33 minutes to complete
During this time Backup drive was mostly utilized at 40% of it's write speed capacity (around 80MB/s instead of 232MB/s that disk can save during big file write).
At first, I thought that calculating backup difference takes a lot of resources but source disk & CPU are bearly utilized. It looks like that you perform a lot of small writes instead of creating proper data in ram and write it in the bigger chunk(s).
Source of this backup is SSD drive capable of reading over 2500-3000MB/s, so it's not a bootlick (even with 4Kb test it will be faster than target HDD).
CPU utilized 13-18% (plenty resources left)
RAM utilized 30-35% (plenty resources left)
Time comparison (142GB Backup)
Summary: Acronis backup time: 33min
Copy this backup file to the drive: 10min
Attaching resource usage screenshots.
