I have uploaded my media backup to MEGA and I am having problems scanning TV shows and Movies. It is really really slow and sometimes my server stops working while it scans the files.
What is your rclone version (output from rclone version)
rclone v1.52.0
os/arch: linux/amd64
go version: go1.14.3
Which OS you are using and how many bits (eg Windows 7, 64 bit)
Debian 9 64bits
Which cloud storage system are you using? (eg Google Drive)
MEGA
The command you were trying to run (eg rclone copy /tmp remote:tmp)
--vfs-cache-max-age 6h (This is the time something stays cached on disk)
--vfs-cache-max-size 100G (This is the size of the disk space the cache will consume)
It's best to start a new help and support topic as that collects all the right information to help you out. I don't see anything wrong in your command offhand.
