Backing up to Dropbox
Keep backups in a folder of your own Dropbox, connected by signing in with Dropbox.
Your servers, agents, WordPress sites and dump containers can back up to a folder in your own Dropbox. Nothing is kept by VPS Snaps.
Step 1 — Sign in with Dropbox
In Storage → Add destination, choose Dropbox, name the destination and the folder to make for it, and select Sign in with Dropbox. Approve access on Dropbox's screen.
VPS Snaps has App folder access only. It can see and write only its own app folder, inside the Apps folder of your Dropbox, and nothing else in your Dropbox. The folder you name is made inside that app folder.
Step 2 — Choose it on a backup job
Pick the destination on any backup job. Each job gets its own folder inside the one you named. To upload, your servers, agents, WordPress sites and dump containers get the destination's own access token, which reaches only the app folder and lasts at most 4 hours; an agent or WordPress site sending a file of up to 150 MB can instead get a one-time upload link, with no token. Restores download through Dropbox's temporary link, which lasts 4 hours; no token is handed out for downloads.
No spare disk, no size cap from VPS Snaps
Dropbox takes a backup as it is uploaded, so whatever makes it needs no spare disk. Backups that pass through VPS Snaps stream through in memory, as they do for S3 and Google Drive, with no 64 MB limit. Dropbox accepts files up to about 2 TB through its API; the space in your Dropbox is the limit.
What to know about Dropbox
Backups count against your Dropbox space. Each backup is checked against Dropbox's content hash, worked out as it uploads. Retention deletes old backups; Dropbox's own deleted-files history then applies: depending on your Dropbox plan, you can restore a deleted file for 30 to 365 days, and deleted files do not count against your space. Your Dropbox sign-in tokens are encrypted with AES-256-GCM before they are stored.
Disconnecting
Delete the destination under Storage. VPS Snaps deletes its stored Dropbox tokens and revokes its access at Dropbox. The backups already in your Dropbox stay there and are yours: open them in Dropbox, or delete them yourself.
