Info: Space requirement on the backup directory

This article is for Zmanda Recovery Manager For MySQL (ZRM) 

The mysql-zrm backup directory (default: /var/lib/mysql-zrm) should have at least 150% of uncompressed backup space available for a successful backup run. This additional space is required even when backups are configured for compression. The additional space is used for compression during the backup run, and is freed after the backup run has completed successfully.

For example: Backup set “dailyset” requires 150GB of disk space for uncompressed backups and backup image upon compression are 100GB. The backup directory filesystem should have at least 225GB (1.5 * 150GB) for space. After the backup run is completed, only a 100GB of disk space will be used.
