Backup Problems "acronis backup & Recovery 11.5
Good Morning,
Guys
I have a backup run with acronis 11.5 that always worked very well without any more problems, and a few days ago I have a bug "Failed to read data from the disk "the backup and saved in a NAS.
Actions taken
- I have formatted the NAS
- I already recorded a file by robocop and it was alright
- I already reviewed the permissions
If anyone has more suggestions, it will be very welcome.

Hello Bruno.
The CRC error means a physical error on the source hard drive (plus there was a "Failed to read data from the disk " error when backing up the same disk to NAS).
Otherwise, there could be a high workload on the backed up drives at backup time.
Please read the respective KB article on how to overcome this issue.
