I'm running rsync (installed from Entware) between an AC86U (local) and AX56U (remote) to move some files between the two routers - both at 384.17.

The command:
rsync -avh --inplace --exclude '*.swp' -e 'ssh -p XXXXX -i /jffs/dropbear/private_key' [email protected]:/[remote_source] /[local_destination]

works as expected for a while, then the following error comes up:
rsync: write failed on "/[local_destination]": No space left on device (28)
rsync error: error in file IO (code 11) at receiver.c(374) [receiver=3.1.3]
rsync: [generator] write error: Broken pipe (32)

How can I avoid the /tmp directory being filled-up? There is plenty of room on the USB drive where the files are being copied to, and --inplace doesn't seem to make any difference.
Any suggestions?


Part of the Furniture
You must be missing the mount point folder name under /tmp/mnt in your rsync command. Therefore, everything is dumping in /tmp/mnt in RAM. Like /tmp/mnt/asus.

Yes, indeed, I had a typo in the [local_destination] which actually created another mount point, hence the leak to /tmp/mnt in RAM.
Thank you!
