Pubky Backup

Pubky Backup is the desktop backup app for maintaining a local copy of published Homeserver data.

Pubky Backup targets published /pub/... data from Homeservers. It complements Pubky Ring: Ring protects identity keys while Backup protects a local copy of published data.

Role in Credible Exit

Section titled “Role in Credible Exit”

Pubky Backup makes credible exit more practical by reducing the risk that a Homeserver outage, policy change, or shutdown leaves a user without a copy of their published data. With a current backup, a user can inspect their own data, preserve a point-in-time snapshot, and prepare a migration to another Homeserver.

Pubky Backup backs up published data and supports snapshots. There is no dedicated tool yet for re-uploading backed-up data to a new Homeserver, but it can be done manually with Pubky tooling such as the SDK. Homeserver mirroring and seamless failover are planned separately.

Limitations

Section titled “Limitations”
  • Published data backup is separate from identity key backup. Keep your Pubky Ring recovery phrase secure.
  • Local backup improves availability and portability, but it is not Homeserver mirroring or automatic failover.
