Who object storage sync is for
Object storage sync is not necessary for everyone. It fits users who already have cloud accounts, understand access keys and bucket permissions, and want their knowledge base data inside a storage boundary they control.
For developers, independent builders, and privacy-aware users, S3, Cloudflare R2, or compatible object storage can make the sync strategy more transparent: you know where the data lives, and you can include it in your own backup and permission model.
- AWS S3 fits users already working in the AWS or S3 ecosystem.
- Cloudflare R2 fits users who prefer the Cloudflare ecosystem and its object storage model.
- Compatible object storage fits people with existing cloud resources and operational habits.
Save and enable your custom source
Add S3 or R2 in Settings → Sync Settings. Enter the bucket and credentials, then save to check the connection. Enabling sync requires Premium.
Custom sync sources give users more control, but they also require users to store credentials, manage permissions, watch costs, and care about service availability. infolio provides the product entry point; your object storage configuration still determines much of the safety and reliability.
Custom sync still needs security habits
If you choose S3 or R2, use a dedicated bucket and least-privilege credentials for infolio where possible. Avoid reusing high-permission master keys. Periodically confirm that a new device can recover the knowledge base.
If your knowledge base includes passwords, IDs, or keys, put them into encrypted vaults before syncing to object storage. The sync source should store objects; it should not be treated as plaintext private-record management.
FAQ
Do I need to understand S3 or R2 to use infolio?
Local editing is free. If you want sync across devices, choose iCloud or another source that all your devices support.
Is object storage sync automatically safer?
It gives you more control over the data boundary, but safety still depends on credentials, permissions, devices, and backups. Sensitive content should still live in encrypted vaults.
