Keep a separate, restorable copy of your workspace; don’t rely on sync alone. First check what the app stores and what its backup actually includes, then save that backup somewhere independent, protect any recovery key, and test that you can restore it. Exact steps and encryption behavior vary by app and platform, so confirm them in the app’s current documentation.
Sync is not the same as a backup
Sync keeps versions of your workspace aligned across devices. A backup is a separate copy intended to help you recover. If a deletion or unwanted change syncs, it may reach every connected device; a separate copy with its own history or destination gives you another recovery point. Obsidian’s help documentation puts it plainly: “Syncing keeps your notes updated, but it doesn’t protect against data loss.” Obsidian’s backup guidance recommends a dedicated tool that makes a one-way copy rather than altering the original.

Think of sync as a way to work across devices and backup as a way to recover from a mistake, device failure, or other loss. A synced copy can still be useful, but it should not be your only recovery plan.

Find out what needs to be backed up
Before choosing a method, identify the app’s data boundary. A workspace may include more than visible note text: attachments, images, audio, files, vault items, tasks, settings, metadata, and local changes that have not synced may live in different places. An export that contains readable notes might omit data needed to restore the workspace as it was.

App storage differs
In Obsidian, notes are Markdown files in a local vault folder, and vault-specific settings are stored in a .obsidian folder at the vault root. Some workspace-layout files change as you open files, so decide whether that transient state matters to your recovery needs. Obsidian also uses a local metadata cache. Its explanation of how it stores data illustrates why copying note text alone may not capture everything you want.
Joplin describes itself as offline-first: data is stored on the phone or computer, and notes use Markdown. Its ability to sync with multiple services, with end-to-end encryption available, is a different architecture from a folder-based vault. Local availability and sync options do not by themselves establish which export or backup will restore a complete workspace. See Joplin’s official app documentation for its current details.
PrivacyNotes documents distinct backup and export options. Its encrypted full backup includes notes, journals, vault items, tasks, images, audio, and files; its text/HTML exports and smaller encrypted backup are different outputs. That is an example of why you should check the purpose and contents of each option in your own app’s documentation, rather than treating every button labeled “export” as a full backup. PrivacyNotes Help & FAQ describes its formats and restore behavior.

Choose a backup that matches your recovery goal
When the app offers a documented full backup and restore process that covers your workspace, use it for disaster recovery. A readable Markdown, JSON, or HTML export can be valuable for portability or access outside the app, but it may not preserve all attachments, app-specific metadata, settings, or restore behavior. Keep those purposes distinct.
| Approach | Useful for | What to check |
|---|---|---|
| App’s full backup and restore format | Rebuilding the workspace in the same app, when the format is documented for that purpose | Included data, supported restore destinations, key requirements, and whether restore can overwrite or duplicate existing items |
| Readable or portable export | Reading notes elsewhere or moving content to another tool | Whether attachments, metadata, and app-specific features are included; do not assume it is a full restore image |
| One-way copy of app data | Keeping a separate copy of a local workspace or data folder | Whether the app is closed or files are otherwise captured consistently, and whether the copy includes all required folders |
Obsidian recommends a dedicated one-way copy of the vault. That principle can help with folder-based apps, but a raw folder copy is not automatically appropriate for every app: first establish where its data lives and whether the vendor documents copying it as a safe backup method.
Keep the copy independent of the working workspace
Choose a destination that is separate from the synced working folder and, ideally, from the primary device. Obsidian’s backup guidance discusses Git-based copies, local backup folders, cloud storage, and external drives. Each has tradeoffs; an external drive can be lost or damaged, while cloud storage requires careful attention to who can access the data and how it is protected. A local external hard drive or SSD can complement an off-site copy, but choose capacity and connections that fit your needs and store it apart from the device when practical. The guide’s destination options are examples, not a universal recommendation.

- Separate location: Avoid making the only backup another folder that is affected by the same sync or device failure.
- Independent history: Prefer a method that can retain earlier copies, so an accidental deletion or damaged change does not immediately replace every recovery copy.
- Access control: For cloud storage or a third-party sync provider, check account security, provider access, and the applicable privacy policy.
- Sustainable routine: Use an automatic process if you can verify it, or a manual process you will consistently remember. No single frequency is right for every workspace.
Joplin’s privacy policy says its apps do not send data without authorization, and that selecting a third-party sync provider sends notes to that provider, whose privacy policy applies. That is a reminder to assess the destination you actually selected rather than assuming all cloud storage has the same privacy properties. Joplin’s privacy policy explains its stated approach.
Understand encryption and protect recovery keys
Encryption depends on the app, the type of copy, and the destination. Confirm whether note text and attachments are encrypted, where encryption occurs, who controls the key, and what metadata may remain visible. Do not infer that a service’s sync encryption also protects a local copy or every export format.
Obsidian says Sync can use end-to-end or standard encryption for its remote vault, but the local vault is not encrypted by Obsidian. Its end-to-end encryption password cannot be recovered by the company; losing it prevents connecting new devices to the encrypted remote data. Obsidian recommends making a full local vault copy before rebuilding Sync. See its security and privacy guidance.

Joplin supports end-to-end encryption, but its documentation says it must be enabled manually on one device and then synchronized to the others. Support for encryption does not mean it is already enabled for your existing data. Check Joplin’s E2EE instructions for the current setup and behavior.
PrivacyNotes says its full encrypted backup uses the account’s phrase key and can be restored with that phrase. Its FAQ also describes a readable ZIP backup that restores into another vault. These are app-specific examples, not general rules. Store recovery keys or phrases separately from the backup, in a place you can access if the original device is gone; losing a required key can make an otherwise intact backup unusable.

Make a backup and verify that it can be restored
- Read the app’s current backup documentation. Confirm the correct process for your app and platform, what is included, and whether the format is meant for restoration or portability.
- Check sync status and local changes. Let sync complete where appropriate, but preserve anything that has not synced before relying on another device or changing devices.
- Create the backup in the documented format. Save it to a separate destination rather than only inside the live workspace or its synced folder.
- Check the backup contents. Confirm that expected notes and representative attachments or other important data are present. Keep the required key or phrase available separately.
- Test a small restore. Where the app allows it, restore into a test workspace or a small set of items. Check whether restoring can overwrite newer work, update existing items, or create duplicates before using it on your main workspace.
- Repeat and review. Verify that the process continues to produce usable copies, and revisit the documentation after app or platform changes.
Restore rules can be more complicated than “put the file back.” PrivacyNotes, for example, documents ID-based matching: a missing note is added once, an existing note updates only under specified newer-copy conditions, and restoring a source without the app’s IDs may create duplicates on repeated restores. Check your app’s own semantics and test before relying on a restore to merge with current work.
Before switching or wiping a device
Do not assume a phone or computer’s built-in cloud backup includes the private workspace app’s data. PrivacyNotes says its Android app data is excluded from the phone’s cloud backup and warns that unsynced data remains only on the old phone. Its guidance is app-specific, but the general precaution is useful: check sync completion, retain a separate backup or export, and verify that you can access the necessary encryption key before erasing or trading in a device. See PrivacyNotes Help & FAQ for that app’s transfer guidance.
