I work for the department of the university, they do not have much money, thus pretty much everything I set up for them is free as in free bear. I have to invest my time and knowledge - and help of others - instead of paid support, and this way I earn my salary ;-) Suits both myself and my employers.

I switched to its fork bareos at some point; I use bacula/bareos for at least a decade.

Add to FDs (file daemons) extra instances of director - offsite one with different passwords for the sake of security. Then there will be a set of everything off site, not only a set of volumes. Of course, if you only have a set of volumes, but everything else has evaporated, you still will be able to restore everything, including database records by scanning set of volumes. Which will take forever. I would alternate dates of backups in offsite/onsite schedules, or define times of backups so that they do not overlap. >> >> Another good news of this vs just rsyncing volumes is: bacula/bareos verifies checksum of every backed up file after receiving it. This will ensure consistency of files in remote volumes, for rsync you will have to at least verify checksum of each volume transferred to destination (unless I miss my wits and rsync does verify checksums of files transferred, I just re-read rsync man and don't see verification - hopefully rsync expert will chime in and correct me if I'm wrong about rsync). >> >> Anyway, that is what I would do. >> >> Valeri >> >>> Thank you in advance >>> _______________________________________________ >>> CentOS mailing list >>> CentOS at centos.org >>> https://lists.centos.org/mailman/listinfo/centos >> >> -- >> ++++++++++++++++++++++++++++++++++++++++ >> Valeri Galtsev >> Sr System Administrator >> Department of Astronomy and Astrophysics >> Kavli Institute for Cosmological Physics >> University of Chicago >> Phone: 773-702-4247 >> ++++++++++++++++++++++++++++++++++++++++ >> _______________________________________________ >> CentOS mailing list >> CentOS at centos.org >> https://lists.centos.org/mailman/listinfo/centos > -- ++++++++++++++++++++++++++++++++++++++++ Valeri Galtsev Sr System Administrator Department of Astronomy and Astrophysics Kavli Institute for Cosmological Physics University of Chicago Phone: 773-702-4247 ++++++++++++++++++++++++++++++++++++++++
