You can do those standard operations once the remote is mounted, but in my experience it can be glitchy. I prefer to mount remotes and treat them as read-only.
You can always use the --dry-run flag to see what rclone would do when running your command without actually doing it. It’s a good way to ensure you hve your paths right, etc.
Can you recommend any other flags which I should add to my copy/move command to make it more reliable/better?
Trying to find the perfect settings for this actions right now. I want to use those commands to upload new stuff (if there is any) to gdrive each night.
The commands themselves are very reliable on their own. Just run rclone check or rclone cryptcheck every now and then to ensure all your files have been uploaded properly.
One more question how can I make sure it is not overwriting existing files?
So I mean it should skip existing files but if the timestamp of an file it newer on my NAS than on GDrive then it should overwrite the old file.
rclone sync skips existing files and only replaces them when the source file has a more recent modification timestamp than the one in the source. There is an error margin it considers before rewriting the file (i.e. a file that was modified 500ms after the original one may not actually have been modified), but I don’t know what that margin is.
You should probably sync your /share/CACHEDEV1_DATA/Multimedia/Video/ directory into a subdirectory in gcrypt2: instead of at the root, because you are keeping the backup directory. Sync may delete your Archive subdirectory.
