Hello. Bacula 5.0.0, CentOS 6.4 x86_64, MySQL 5.5.34. Bacula was installed from CentOS Remi repository. Bacula server: bacula-dir, bacula-sd. Bacula client: bacula-fd. Both machines are in local network and have 1Gbit network cards. Maximum io capacity on bacula server is about 180 Mbytes/per sec (tested). Backups are stored on disk, no tape drive used.
Bacula client is a machine with 1.2Tb data (over 1M files). When I enable compression on the client (compression=GZIP), backup performance is extremely degraded, network interface load is down to 100 Mbit/s. Then I disable compression, restarts backup and achive up to 500 Mbit interface load. Looks like good: 500Mbit/s - 1.2Tb data backup time is about 6 hours. But I want to store files compressed on the backup server to reduce disk space usage. I googled up it and found that no way to enable server-side compression in Bacula. Also I found that people are disables compression in Bacula and store volumes on filesystem with compression support, like ZFS. I think that no good result in this way because Bacula had it's own archive binary format and volume (like binary file) compression by any external algorithm must be ineffective (~ 1.1:1 ratio). Ways to resolution problem? 1. Backups uncompressed, then unpack volume with external tools, compress and pack again. (..How Bacula does operate with that again? No way..) What else? I want to store files in volumes compressed without losts network copy performance.
