ATI2017 full backup slowed down from 2 hours to 20
I do 2 90 gb full backups weekly from C: disk all partitions
one to an internal hard disk G: ( takes 45 min approx) running for years
one to a portable Usb3 to usb3 disk H: ( takes 2 hours approx) running for years
Recently backup to disk H: started taking 20 hours plus
I have tested the backup on same USB 3 to a crucial 256 gb ssd (takes 20+ hours) also tried another usb3 port to no avail.
I have checked settings and advanced setting in ATI and all looks good.
error checking on the H: disk revealed perfect health.
My windows 10 is fully uptodate.
A fresh insight would be appreciated.
FURTHER INFORMATION
Thankyou for the reply Steve.
I have some more info that possibly questions your reply. I have run some disk throughput tests using Microsofts winsat app.
Crucial Test SSD refered to above:
USB2 USB3
Random 16.0 read 24.85 MB/s 272.25
Sequential 64.0 read 31.5 MB/s 384.75
Sequential 64.0 write 31.02 MB/s 382.06
Avg read time seq writes 1.15 ms 0.253
Latency 95th percentile 2.208 ms 1.122
Avg read time with random writes 1.168ms
As you can see the disk throughput is about 10 times better on USB3
The same USB,s same cables, same test disk ???????????

John, since using MR has shown that this issue looks to be only happening for ATI 2017, then I can only suggest looking at KB 60915: Acronis True Image: repairing program settings - and using the method shown for doing a Repair Install of ATI 2017 to see if this will bring back the normal, expected performance with your USB drive.

Trying the repair procedure part 1 and part 2 to no avail.
Decided to do a fresh install of Trueimage2017 and low and behold the full backup went down to 18 minutes HOORAY (originally was 2hours degraded to 20 hours suddenly)
Thankyou Steve Smith for your help.
