+Google Drive & RClone: Backing Up, Syncing & Copying
+====================================================
+
+Rclone supports several modes of syncing:
+
+  - "sync"
+  - "copy"
+
+What are the differences?
+From rclone's website:
+
+>   "Sync the source to the destination, changing the destination
+    only. Doesn't transfer files that are identical on source and
+    destination, testing by size and modification time or
+    MD5SUM. Destination is updated to match source, including deleting
+    files if necessary (except duplicate objects, see below). If you
+    don't want to delete files from destination, use the copy command
+    instead."  ([ref](https://rclone.org/commands/rclone_sync/))
+
+Unless you want to perform deletion on the destination to match 100%
+what's on the source, you will want to first look at the "copy"
+operation.
