Bupstash is a tool for encrypted backups - if you need secure backups, Bupstash is the tool for you.

Bupstash was designed to have:

• Efficient deduplication - Bupstash can store thousands of encrypted directory snapshots using a fraction of the space encrypted tarballs would require.
• Strong privacy - Data is encrypted client side and the repository never needs has access to the decryption keys.
• Offline decryption keys - Backups do not require the decryption key be anywhere near an at-risk server or computer.
• Key/value tagging with search - all while keeping the tags fully encrypted.
• Great performance on slow networks - Bupstash really strives to work well on high latency networks like cellular and connections to far-off lands.
• Secure remote access controls - Ransomware, angry spouses, and disgruntled business partners will be powerless to delete your remote backups.
• Efficient incremental backups - Bupstash knows what it backed up last time and skips that work.
• Fantastic performance with low ram usage - Bupstash won't bog down your production servers.
• Safety against malicious attacks - Bupstash is written in a memory safe language to dramatically reduce the attack surface over the network.

Stability and Backwards Compatibility

Bupstash is alpha software, while all efforts are made to keep bupstash bug free, we currently recommend using bupstash for making REDUNDANT backups where failure can be tolerated.
