Repeated Data Corruption Errors
This problem has happened to me 6 times in 2 years. During an incremental Daily backup using Acronis True Image 2019 for Mac, I'll get:
The last backup attempt failed. Read error or data content is corrupted.
I'm backing up to a Synology NAS, which I've checked repeatedly for disk problems and found none. I've filed several support tickets, only to be told to start another full backup (which takes 5 hours). This solves the problem for anywhere from 2-4 weeks, then I get it again.
This is not right. If a backup program encounters a read error then it should make a reasonable attempt to fix the problem. At the very least, it should leave the corrupted file in place and backup the file in another location.

Hello Craig,
I haven't found any known solutions for the issue apart from re-selecting the backup source in the backup plan and\or starting a new backup chain. Finding the root cause of the failure would require more in-depth investigation with the help of our support engineers. If you can spend some time for investigation, please open a support ticket and share the ticket ID with me, I'll try to prioritize it.
