Backups remain to fail - " no space left on device " , Yet I have TBs of free space and RAM doesn't seem to be an issue also

I have searched around and haven’t been able to find a comparable issue. My destination is a CIFS share over a 20Mbit/s VPN Connection. I have had many backups of various sizes complete with no issues but it seems when I start to attempt to backup 10+ GB in a single run I have such issues " No space left on device" yet the destination share has over 2TB free…

I thought maybe this could be a RAM or Local space issue that Dupliacy is running on, and it’s not. Plenty of free space on the cache drives 400GB + and plenty of free RAM, the server has 24GB using around 8GB

  1. Maybe the error message is inaccurate, and it just fails to create a chunk locally? do you have enough space on local /cache volume?
  2. if the error message is accurate I woulds blame SMB/CIFS server issues, assuming there is indeed plenty of space on the target.

Generally (regardless of the outcome of this failure) I would recommend switching to password-less key or certificate based SFTP; that one would be rock solid and as a bonus you won’t need to push all that data over VPN and performance will improve too (SMB is sensitive to latency).

Thanks! Yes I changed to SFTP… I didn’t think about it until after my post… I recently changed to Dupliacy from another product and SMB was my only option then.
