Re: [Bacula-users] Should I have a server in every location?

I’m brand new to Bacula. Getting some good information from the list. As I’ve mentioned before, I’ve got three offices in different locations. I’m needing offsite storage of data as part of a disaster recovery plan. I’ve got a couple of questions

·        Should I have a server in every location?

·        Can Bacula servers send data between each other?

Here’s my thinking

1.      Local backup in case someone deletes a file

For just restoring a deleted file on occasion, local backup is not needed. Only the restored file(s) will be transmitted. For restoring entire machines, a local backup will be much faster.

Whether or not to have local servers depends on several things. In addition to the expensive of separate tape hardware, tapes, etc. at every location, it is an administrative headache. Tapes must be handled and stored at each location. An operator is needed at each location to load and change tapes and to manage sending tapes to the offsite location, etc. It may mean more people have to be trusted with sensitive data. Branch to main office network bandwidth must be considered. Local servers may be the only choice if bandwidth is limited. On the other hand, centralized backup may be the only choice if the remote sites do not have the personnel. So it really depends on which scenario will be the best fit for your organization.

2. Use another remote server for offsite storage

It is possible. Backup jobs on local volumes can be migrated to volumes at the main site over the wire. It of course requires the same bandwidth as if the job were written to a main site volume directly, but the migration can be scheduled for off hours and writing to local volumes allows client jobs to finish much faster.

Thanks!
