Why is AOMEI Backupper Professional so slow?
I have 5 SSDs on my computer with about 12 TB of data in total. The problem is backing up even one of those SSDs is extremely slow. For example my main system drive, which has 2.5TB out of 3.7TB used. I configured a System Backup for it, with weekly full backups then daily incremental backups. It's currently backing up at only about 60MB/s, and it will take 9 hours to complete the backup, which is an incremental backup should be very small compared to a full backup, as I didn't add or change many files in the last 24 hours. I'm using "Intelligent Sector Backup" and VSS, normal compression, if it matters.
And no, it's not the NAS where I do my backups being slow. Because this is an incremental backup, and so far has written only 16GB to the NAS in about an hour (so about 0.27 GB/minute or 4 MB/s on average).
My SSD is a Kingston Renegade Fury 4TB which should have read speeds of up to 7,300 MB/s. The backup is more than 100 times slower than that, at 62 MB/s.
The problem is not the CPU, it's currently using only around 1% CPU on my 13900K.
So, I don't know. It could be because there are many small files on my drive? Maybe I should change it from a System Backup to a regular Disk Backup? What exactly is the difference?
Finally, I feel the need to add that don't like this software at all, it's too inflexible. First of all, the Backupper is keeping my computer hostage for days while backing up, which is very frustrating. Right now it has been backing up for 14 hours continuously, for example. You can't even check the settings for the backups or change them while it's backing up. You can't pause the backups if you have something to do and don't want the backup to slow you down, but you don't want to cancel it and lose the progress either. You can't reboot while the backups are running. And if you try to to reboot the Windows reboot sequence starts, blocking your access to the Windows UI, then the Backupper prevents the reboot from actually occurring until the backup completes, with no option to cancel the backup, so you can't use your computer for hours if you forget to check that the Backupper is running before rebooting. The only option in that situation is to force a power cycle on your computer, which could potentially cause data loss.
Also, the backup email notifications don't work. I have them configured with AOMEI server, the test email arrives, but I get no notifications when backups complete or fail.

Backupper compression setting "None, Normal, High", will affect the backup speed.
What file system is your target disk? ExFAT filesystem, created in 2006, is slightly faster than NTFS, created in 1993.
Backupper may at times go slower than desired, but usually it will go at the speed of your disks, cable, ports, file systems, and data file types. If you want an affordable external disk with consistant high speed, try the Crucial X9.
