Bacula will not reassign the device of a running job. For example, if a job is writing to a volume from pool A on device 0 and that volume becomes full, then it will seek another volume to write on. If the next selected volume from pool A happens to be in device 0's library, then all is well. However, if the next selected volume from pool A resides in the other autochanger's library, then it becomes a huge problem and Bacula will be forced to ask the operator to move the tape manually from one library to the other. One possibility is to use a different pool for each job, then keep all tapes from a particular pool in the same library. For example, place tapes for pools A, C, E in device 0's library and tapes for pools B, D, F in device 1's library. > Thanks all for your time and consideration! > > --eddie > -- Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
[Bacula-users] Multiple autochanger devices
Hi all, Looking for a bit of suggestion or direction here. Keep in mind, RTFM is a valid response so long as you provide some hints as to which M to R where. 😀 I have a pretty straight forward setup using bacula 7 on centos 6 and two tape libraries attached via FC to the host. Using a single client to backup several nfs/cifs mounts to lto5 tape. This setup has given me some three years of mostly headache free backups. What i have been unable to accomplish is having both changers available for all jobs coming from this single client. Couple of questions, Should I be using multiple clients or storage daemons? I already have the single sd configured to use both devices, how can i tell dir or client to pick a free tape device from ANY changer when client starts job?
