Have you checked permissions for writing the specified directory? Take a look at the error time:
>>>>>>>>>>>> 08-Sep 11:51 BS01-SD1 JobId 12897: Forward spacing Volume
>>>>>>>>>>>> "mail-0386" to file:block 0:219.
>>>>>>>>>>>> 08-Sep 12:14 BS01-SD1 JobId 12897: End of Volume at file 28 on
>>>>>>>>>>>> device "File_bluewhale" (/nas/bacula/bluewhale), Volume "mail-0386"
>>>>>>>>>>>> 08-Sep 12:14 BS01-SD1 JobId 12897: End of all volumes.
>>>>>>>>>>>> 08-Sep 11:52 BS01-FD1 JobId 12897: Error: create_file.c:292
>>>>>>>>>>>> Could not open /nas/users/admin/backups/data/backups/mail/fifo/mail.tar:
The error takes place before the end of volume is reached.... Does it means that Bacula cannot write the file to the restore directory specified or not?
