I am considering switching to Dropbox Plus from Google One, the problem I have with Google is that everytime i restart, or make a change to a folder it takes about 1 day to "process" all of the files before it starts to upload anything, this means to upload large amounts of I have to leave my computer on for multiple days and can't restart it or it has to start over, sometimes it takes more than 1 day.
I am syncing a little over 1TB of data, does Dropbox Plus work faster? if I restart does it pickup where it left off? does it have to process everything each time a change to a folder is made?
In general, syncing can take time depending on the number and size of the files you have. When Dropbox syncs the files it starts with all of the folders, then uploads files from smallest to largest.
For this reason, it may look like the folders are empty or incomplete if you look during the syncing process, but please be patient and don't delete them from the Dropbox folder if the files haven't finished syncing.
Also, if the desktop app is offline (not connected to the internet), upon connecting again, it will try to index for any changes that occurred.
Although Dropbox can only upload and download as fast as your ISP allows and it tries not to use all of your bandwidth, you can change that by manually changing the desktop app's upload/download speed.
