> 1) Can we tune bacula config files for maximize backup speed? Turn on attribute spooling to save on database round-trips during the backup run (these will be inserted at the end). Try to measure where your bottleneck is and then see if you can do anything about it: read I/O on the FD machine, network throughput, write I/O on the SD machine.
> 2) Can bacula use both tape drive simultaneous backup for same pool? You can use multiple drives to write multiple volumes from the same pool concurrently, but each drive would need to be writing for a different job. You cannot split a single job across multiple devices. > 3) Any other suggestion/tips? I had problems with big backups (multi-TB) taking too long (>6 days). I got around this by taking a block-level backup using the bpipe plugin instead of a file-level backup. I'm using ZFS, so send/recv but if you're using another system it could be done with LVM/Btrfs or even tar. These run much faster because the underlying disks can provide big sequential reads, and there's no need to deal with individual file metadata. The downside is not being able to restore individual files, and having to have enough scratch space to restore an entire backup if you need data from it. So it's a compromise, and it's up to you whether this would fit with your workload. Regards, Ben Roberts P.S. This is the second time John Drescher has just beaten me to a posting today!
