2GB error with current driver

Recommended Posts

I just upgraded to an Intel Mac. I downloaded Retrospect 6.1 and the latest drivers that I could find. I still get an error message saying that there is a 2.0 G limit. Full report folllows. Advice?

Can't add that much data to backup set.

The limit is 2.0 G.

What type of backup are you doing? File Backup? Check the formatting of the disk to which you are backing up. I bet that it is not HFS+, but instead is FAT32 (PC formatted), which has a 2 GB file size.


Reformat as HFS+ and it should work.




Not quite correct: FAT32 has a 4GB file size limit.

Old versions of AFP (Apple Filing Protocol) has a 2GB file size limit. Are you backing up to a network disk?

I installed the latest RDU (, and I am now able to backup to a file on a LaCie Ethernet RAID 2 TB NAS connecting with SMB. Before the update it failed saying the backup set would exceed 2gb. I did not reformat the drive, only replaced the driver. I have completed one file backup of 38gb and almost done with a second that exceeds 50gb. The RDU definitely seems to have helped that issue. (Now I have a new one for another post.)
