All:
A month ago, I polled the Bacula user community to identify the predominant configurations in use for
the purposes of outfitting a test environment for regression testing. Although the initial request was simply
for the OS in use, the amazing level of detail provided by many respondents enabled me to add information
on both catalog database and number of directors, storage daemons, and file daemons. The results were
quite interesting and I share them with you below:
[ SUMMARY ]
Total people who responded.....................: 50
Total number of Bacula servers (director + sd).: 108
Total number of Bacula clients (fd)............: 991
Average client-to-server ratio.................: 9:1
[ OPERATING SYSTEM ]
Number of Linux responses......................: 36
Number of FreeBSD responses....................: 9
Number of Solaris (Sparc and x86) responses....: 4
Number of HP-UX Responses......................: 1
Number of Linux distributions..................: 8
CentOS
Debian
SuSE
RHEL
Fedora Core
Gentoo
Ubuntu
[ CATALOG DATABASE ]
Number of MySQL responses......................: 24
Number of PostgreSQL responses.................: 14
Number of SQLite responses.....................: 5
[ SCALE ]
Responses with more than 100 clients...........: 2
Responses with more than 50 clients............: 5
Largest tape library dedicated to Bacula.......: STK L700e (300+ slots)
Not included in these results is the distribution of client operating systems (there were too few responses that
listed these with numbers and I did not ask). However, out of those that provided this information, all supported
client OSes were to be found, including a surprising number of predominantly Windows environments backing-up
to a central Bacula server. Although the typical Bacula server is running Linux today, it is protecting data on systems
running just about every open systems OS that is out there. Additionally, the handful of responsents that included
notes on how much data they back-up (again, something I did not ask for), indicated that they are handling backup
volumes well into the terabytes.
Thank you again to everyone who responded, especially to those who provided detail above and beyond that
asked for. The information will be put to good use in the design and configuration of a build and regression testing
environment that will reflect as much as possible the environments in use within the Bacula community.
Kindest regards,
Peter Buschman
