Replication & Durability
Each object is written to three nodes, so one dead disk never takes a file with it.
Desktop app · v0.1.0
Storage that survives failure.
Vault copies every file to three storage nodes. When a disk dies or a machine drops off the network, your photos, backups, and datasets keep serving, and the missing copy is rebuilt automatically.
Windows, macOS, and Linux. Runs a local cluster on your own machines.

Features
Built for the day something breaks.
Disks wear out, laptops get unplugged, and cables get kicked. Each part of Vault handles one of those failures, so files stay readable through them.
Auto-Repair
When a node drops, missing copies are rebuilt from healthy replicas without anyone getting paged.
Corruption Detection
Checksums catch silent bit-rot on read, and the bad copy is replaced from a good one.
Partition Tolerance
If a flaky switch splits the cluster, reads keep flowing and both sides reconcile on reconnect.
Metadata Consistency
Nodes agree on which buckets and objects exist, so a file never half-disappears.
Rebalancing
Add a machine and data spreads onto it gradually, with no maintenance window.
How it works
Watch a node fail and heal.
This is the loop Vault runs whenever a machine disappears: notice it, copy what was lost from the survivors, and prove the data is intact.
- 1
Detect the failure
A node stops answering heartbeats. Every object it held is flagged as down to two copies.
- 2
Re-replicate from neighbours
The two nodes that still hold those objects send the missing copies back into place.
- 3
Verify and return to 3/3
Checksums confirm each rebuilt copy before the cluster reports itself protected again.
