Compression and Encryption in Aerospike’s Backup Tool — Asbackup
Blog post from Aerospike
Aerospike Backup (asbackup)` is a tool used to backup and restore namespaces in an Aerospike database. The new feature added allows for compressing and encrypting backup files as they are being made, ensuring data security even if the backup job is aborted before finishing. This is achieved by operating on the data before it is written to the file, preventing unencrypted data from being stored on disk. The compression algorithm used is `zstd`, while encryption is done using `AES 128/AES 256` in Counter Mode, requiring a private key for decryption.
