Error fffffffe occurs during a file backup
The error code "Error fffffffe" normally will show in a file backup for one of three reasons. If your destinationstorage location is out of disk space when it goes to store that file in to the backup set that is being created on that destination storage location. This same error code can mean that the network connection, which is making the connection from your source computer to the destination NAS/SAN/network share has dropped or was interrupted. If the network connection between the source and destination NAS/SAN/network share, etc. is dropped or interrupted then this error can occur as well with the same error code.
In either case what you can do is first check on the free disk space. If this happens often and it does not seem to be free disk space related then you will need to investigate the network infrastructure that connects the two devices together to facilitate the network backup. NovaBACKUP SMB products such as Pro, Server and Business Essentials will not re-try a dropped network connection and cannot handle an interrupted network communication. If your destination storage location was a locally connected drive or a USB drive then read further on a special note on file systems support.
If your destination storage location is a local drive or USB connected hard drive:
This error can also occur if the destination storage location's file system is FAT or FAT32 (read the guide here orhere) and you are including individual files over 4GB in size. NovaBACKUP requires a file system that can handle large file storage including NTFS and most file systems that a NAS would come with. Brand new off the shelf hard drives may have come formatted as FAT32 which have a 4GB per file size limit. Check your destination storage device file system properties appropriately.
Either way, if you receive that error a partial backup will be left on the destination storage location either because the network connection was dropped or if the destination storage location ran out of space or the special note about file systems above. Please attempt to look at these items prior to calling NovaStor Technical Support for this type of question scenario.
