Bacula has 3 components. There is a Director, Storage, and File. Storage is the component that handles direct access to the storage component. File is the component that sits on your server to be backed up with access to the local file system. Director is the component that handles scheduling and telling the file component where to contact the storage component. All three components can live on the same machine. In fact, even when scaled up, you will likely have at least a Director and a File component on the same machine. Part of the benefit of running Bacula is the ability for it to identify what files are needed between backup runs. For instance, our file server is fully backed up on the first Sunday of every month. Then we do incremental backups each day, Every Sunday except the first has a differential backup. This means worst case restore would be a Saturday before the full backup. We would have to read the Full Backup, then 3 or 4 differential backups for the weeks in between, and then a weeks worth of incremental backups. All that to get a look at the files that existed at the end of the last backup. Makes for a fast restore. Our current backup solution has our backups going to 3 500gb drives joined with lvm into one large striped setup. We have bacula splitting backups into 10gb files since bacula uses drives like tapes and reads from the beginning in. 10gb then is the worst lost read time to get to the end of the storage. The python script I linked to earlier had 5gb limits so it could upload them to Amazon's S3 service. One other thing I learned about bacula is that the sqlite driver doesn't do well over long periods of time due to the need to vacuum the db regularly. I didn't realize that originally and the vacuum took way to long to finish. -- Steven Critchfield [EMAIL PROTECTED] --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "NLUG" group.
