I've tried this, but I've had sync issues in the past. Also have they gotten rid of their 2GB file upload limit?
There is no 2gb limit that I have run into. I just checked and I have several >30GB videos uploaded to my cloud drive, so I can safely say there is no issue there.
Edit: For some completeness, here's how I have everything mounted and syncing.
acdcli mount /mnt/amazon_real --interval 30000000 -ao --uid 112 --gid 118
unionfs-fuse -o cow /mnt/cache=RW:/mnt/amazon_real=RO /mnt/amazon -o allow_other
0 * * * * acdcli upload --remove-source-files /mnt/cache/* /TV/ --max-connections 10; acdcli sync
And that's it. The last one is a cronjob that runs every hour, if that wasn't obvious.In the first line you mounted your whole Cloud Drive at /mnt/amazon_real. On the 3rd line you upload from /mnt/cache to /TV/.
Do you actually have a subset of the cloud drive mounted at /mnt/amazon_real? I tried to do that some time ago with acd_cli but wasn't able.
I have not looked into only mounting a section of it.
