The need
Knowing whether a backup finished.
DHN’s working files are in Google Drive. I built Vault to manage copies at the office and offsite, with a way for staff to check that the scheduled jobs had finished.
What I built
Working files, an office copy, and an offsite backup.
The setup has three tiers: Google Drive, a local mirror at the office, and an offsite backup in Backblaze B2. Vault copies files between them on a schedule.
Staff can change the schedules and watch transfers from the dashboard. Completed jobs and failures stay in the history, so a failed copy is visible without opening a server log.

Deleting a file can remove it from synchronized copies too. Older versions need to be kept separately.
Implementation
What the backups keep, and what they don’t.
Synchronized copies and deletion
These copies stay synchronized, which means a deleted file can disappear from the copies too. Keeping older versions for recovery needs to be configured separately.
Transfer previews and cleanup
A transfer can be previewed before it runs. Staff can also check what a scheduled cleanup will remove.
