Percona is glad to announce the release of Percona XtraBackup 2.1.0-alpha1 on April 2nd 2013. Downloads are available from our download site here. For this ALPHA release, we will not be making APT and YUM repositories available, just base deb and RPM packages
This is an ALPHA quality release and is not intended for production. If you want a high quality, Generally Available release, the current Stable version should be used (currently 2.0.6 in the 2.0 series at the time of writing).
This release contains all of the features and bug fixes in Percona XtraBackup 2.0.6, plus the following:
Percona XtraBackup now has support for Compact Backups. This feature can be used for taking the backups that will take less amount of disk space.
Percona XtraBackup has implemented Encrypted Backups. This feature can be used to encrypt/decrypt both local and streamed backups in order to add another layer of protection to the backups.
innobackupex now uses Perl’s DBD::MySQL package for server communication instead of spawning the mysql command line client.
After being deprecated in previous version, option --remote-host has been completely removed in Percona XtraBackup 2.1.
