Your data, in a vault
that never closes.
SmartDiff routes only what changed — at the bit level. Zero-knowledge encryption keeps the keys with you. Multi-tenant isolation by design. Built for the WordPress sites that cannot go down.

Backup engineering you don't have to babysit.
Built by people who got tired of 2 a.m. restore failures. Every line of SiteVault is in service of one rule: when the moment comes, the backup works.
SmartDiff delta engine
Chunk-level deduplication with bit-level analysis. Daily backups shrink from 1.2 GB to 23 MB without losing any fidelity. 87% less data on the wire and on the bill.
Selective table-level restore
Recover one plugin, one theme, one media folder, or one database table. Don't restore your entire site when you only need to undo one mistake.
Multi-tenant isolation
Every customer's chunks live in a strictly isolated namespace. No accidental crossover, no shared storage pools, no scary surprises for agencies running hundreds of sites.
Zero-knowledge encryption
AES-256 for data, RSA-4096 to wrap the keys. Keys are generated on your server and never leave it. Not even we can read your backups.
Pre-backup malware scan
Every backup pass scans for malicious changes before the data leaves your site. If it's compromised, you'll know before it's archived — not after you restore.
WP-CLI native
Scriptable from your deploy pipeline. Trigger backups, list restores, rotate keys, and reconfigure providers without ever opening wp-admin.
The SmartDiff advantage
Most "incremental" plugins copy whole folders. SmartDiff analyses files at the bit level, identifies identical chunks across your entire site, and uploads only what's genuinely new. Move a 1 GB media folder? You'll upload kilobytes.
