I do a full backup (from some pc) on two nas (WD) on the local network. On the first (older) works correctly. On the second I can not complete the backup: the abort occurs with error 59. The backup ends correctly (file saved is 115 Gb) The final message is: Backup aborted! - 'D07CD4EB087594E9-00-00.mrimg' Verification failed at 0% (85248 bytes Error reading from file. Error code = 59).
