Choose ongoing backup or a one-time send
A selected-file backup rule links the files you mark to a cloud folder. Later edits can update those remote copies according to the rule's settings.
Quick Upload sends a selected file to a saved destination and stops tracking it afterward. Use it when you want to send today's version without setting up ongoing synchronization.
Give each destination a recognizable button
Create the rule, choose its account and remote folder, and pick an icon. Use that button while viewing a photo or with a selection in the gallery.
Saving a selected-file rule does not upload the whole album. Files participate when you mark them. Follow their uploads in Tasks.
Check what removing a mark will do
Selected-file rules can delete the remote copy when you remove a mark; this is enabled in the starting settings. Switch that behavior off if unmarking should leave the cloud copy alone.
Backing up to a folder does not automatically make it public. Sharing that collection is a separate choice controlled by your provider and its permissions.
Questions before you start
Can I send files from another Android app?
Yes. Use Android's Share menu to send files into SyncGallery and choose an available destination.
Will changing a sent photo update its cloud copy?
With an ongoing selected-file rule, it can, according to the settings. With Quick Upload, it will not be tracked after that upload.
