We set up a box with a RAID5 array to store backed-up data 2. Do one full backup of all of our data (about 1TB) before taking the machine off-site 3. Do monthly full backups of the data, with daily differential backups (rather than incremental) to make restoration reasonably quick (daily backups amount to ~50MB max) Having talked to someone on the #bacula IRC channel, they've suggested we start with a Base backup type, so my strategy would be this: 1. Create a Base backup with the machine on-site 2. Configure monthly Full backups based on the base, to run off-site 3. Configure daily differentials as per normal 4. Set up bacula-fd to encrypt all data submitted as per instructions online 5. Set up SSH tunnels into the office to run bacula over Does this sound reasonably sensible? Consider using virtual full backups instead of normal full backups. Virtual full jobs take the previous base+full+diff+incremental jobs and merge them into a single full job. A virtual full requires no interaction at all with the client, so is a good match for backup over a slow link. You might also consider using daily incremental backups, rather than daily differential backups, since that would also cut down on FD to SD transfers. -- This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
Re: [Bacula-users] Long-term off-site storage with Bacula
That's the approach I was considering; with the scenario you've outlined, you mention both diff and incremental jobs. Would this mean 1 Base + Monthly Full + Weekly Diff + Daily Incremental? Thanks!

Would this mean 1 Base + Monthly Full + Weekly Diff + Daily Incremental? Yes, because a Diff job backs up all file changes since the last successful Full. An incremental backs up only the changes since the last successful job of any level. A daily Incremental will backup only the changes for one day. A daily Diff will backup one day of changes on the first day, 2 days of changes on the second day, ... , 30 days of changes on the 30th day. So daily Diff will result in much more data being transmitted than will daily Incremental backups. So when backing up over a slow link, 1 Base + Monthly Virtual Full + Weekly Diff + Daily Incremental will be less taxing on the slow link than 1 Base + Monthly Full + Daily Diff. -- This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
