4$ plakar config remote set mys3 secret_access_key <SECRET_KEY>
5# Optional: disable TLS verification
6$ plakar config remote set mys3 use_tls false

Supported options:

  • location: Full S3 URL, e.g. s3://s3.<region>.amazonaws.com/mybucket.
  • access_key / secret_access_key: Your provider’s credentials.
  • use_tls: Enable or disable TLS (default: true).

Questions, Feedback, and Support

Q&A

Do you support all S3-compatible providers?
Yes. If your provider isn’t listed above, reach out on Discord and we’ll help you configure it.

When versioning is enabled, do you back up all object versions?
No, Plakar backs up only the latest version of each object to avoid redundant storage.

Can I replicate between buckets?
Use Plakar CLI to push snapshots from one bucket to another by configuring multiple remotes and using plakar at commands.

Security by design

Reduce your attack surface by keeping encryption keys out of storage. With true end-to-end encryption, your data is protected before it leaves the source and remains unreadable even to your storage provider.

  • End-to-end encryption with modern crypto (no compromise on "at-rest/in-transit")
  • Immutable snapshots with verifiable integrity
  • Tamper-proof metadata and audit logs
  • Zero-trust-friendly architecture
"You don’t have to trust your storage provider."
