MacBook Pro backup is taking a LONG time (15 hours or more)
Greetings - I have 2 identical 2017 MacBook Pros. 500GB SSDs, 16GB RAM, running High Sierra (a little old). They both have roughly the same amount of data (250GB). Acronis True Image 2020 is installed on both of them. I am using a single USB 3.0 external backup drive to backup both of them, one at a time.
On the 1st laptop I plug the backup drive into a USB port and a full backup takes 1 hour 5 minutes. On the 2nd laptop I plug the backup drive into a USB port and a full backup takes OVER 15 HOURS. I don't even trust it. I tried both USB ports on the 2nd laptop.
My first thought was that something has to be wrong with the SSD on the 2nd laptop. BUT I have run several disk checkers on it and it checks out perfect w/no issues. Same OS, same ATI install, etc. I am at a loss to explain this.
Does anyone have any ideas why the 2nd laptop backup is taking so much longer to backup ???
Thanks in advance - Mark
