What's your internet speed? (In particular upload)
I have a GDrive and Onedrive (For Business) that I sync daily using my Gbit connection. I basically keep OneDrive as a failover in case Google ever goes down (I've switched a couple of times and works like charm) with the following command in cron:
the last part: 2>&1 simply makes sure nothing is displayed when running the command to avoid cron making a mail, and I log everything to a file where I can check every now and then to make sure nothing is broken.
I noticed 160M for chunk-size works pretty good and is a multiple of OneDrive and Google factors so it works either way I need to sync.
I keep the transfer number low as I'm sometimes using the same client id for my mount.
Be sure to use Chunker with OneDrive if it's for business as file size limit is 15GB which might be a problem depending on your setup.
Finally, once a month I login to OneDrive and delete the trash sometimes as I arrange my data etc. recycle bin adds up and takes space. Can't be done from rclone so need to manually do it.
Otherwise it works pretty well and usually get over 100mbps transfers, as I sync daily, there is not a lot of data to sync (sometimes nothing) so it takes around 5-10 minutes.
My local connection is 300mbps
Anyways i tried this on a seedbox (ultraseedbox) where running a wget command i can see a burst and speed of 100MBPS to 120MBPS
however running the below rclone copy command, the max I can get is 30MBPS
