TwinDB Backup¶
TwinDB Backup is a multipurpose tool for backing up MySQL database and regular files/directories on the file system. It can store backup copies on a remote SSH server, Amazon S3 or Google Cloud Storage.
TwinDB Backup accepts a backup copy stream from any of supported sources (MySQL Server, Percona Server, Percona XtraDB Cluster, or file system) and redirects the stream to a series of configurable modifiers.
The modifiers can compress the stream, encrypt it, and save a copy of the stream on the local disk.
Compression options:
gzip
bzip2
lbzip2
pigz
Encryption options:
Public/private key encryption
Because TwinDB Backup encrypts the stream itself it ensures transfer encryption as well as encryption at rest.
After the stream passed all modifiers it is sent to one of the configured backup destination. It can be:
Amazon S3 bucket
Google Cloud Storage bucket
Any server with SSH demon
