1.4.0 — optional cloud-folder backups

Released on latest/stable · revision 6 · November 7, 2026. Operoso 1.4.0 is the current stable release, available from the Snap Store. This is the same package accepted with an existing Google-synced folder and released to beta on November 5, promoted without rebuilding.

• Choose a private folder already synced by Google Drive, Dropbox, OneDrive or another provider. No cloud login or provider API is added to Operoso.
• Save verified SQLite copies of all workspaces. Checks run at startup, every 15 minutes while open and when closing; changed data produces a new automatic copy.
• Use Back up now for a manual copy. Keep the latest 30 automatic copies per installation; manual copies and other installations’ backups remain.
• Remember the folder across restarts, see the last local save and get warnings when the folder is unavailable or a write fails.
• Restore a downloaded copy through Preview import as new workspaces. Existing records are not overwritten.

The working database stays local. Your sync client handles cloud upload: a local save does not confirm remote upload. No backups run while Operoso is closed. Copies are not encrypted by Operoso. This is backup, not simultaneous multi-device editing. Read the cloud-backup guide.
