Semaphore Timeout
I see this has come up now and then. I have been using Acronis since version 10 with lots of different external media. I have used it for a year with my hardware USB 3.0 RAID 1 (2 WD Black 1TB). I had problems with my 1st backup using 2018 (validation failed) and my 2nd (semaphore timeout) with the RAID array but not with other external drives. Acronis support so far seems not up to the technical challenge.
I have run (and continue to run) WD utilities to test the drives. Different utilities showed no issues and I suspect the current one that takes 2.5 hours per drive will not either.
Any ideas on this? My next move will be to turn off the Acronis Active Protection since that has shown up here and there re semaphore timeout
Regards, Mike

Thanks Steve. I saw a reference back in 2012. Some references on these forums and elsewhere focus on network adapters and others on HDD errors. Pretty sure mine is neither. I have no way to test my RAID controller but am still working on that. I went from RAID 1 to JBOD and will try a backup to each of the drives.
And I will also try to turn of all anti-virus, firewalls, etc. since those have come up. Still feel it's odd that this started with 2018.

More info. I changed my RAID 1 array to JBOD and just backed up and validated successfully on 1 of the drives. I found nothing of help on semaphore. I will pursue possible issues with the RAID controller.
