Hi Team,
We have installed Bacula-7.0.4 on CentOS 6.5.
Have configure Autochanger with 2 LTO-2 drives.
For testing I have configure 5 clients to be backup on tape.
Total size of clients are around 800 GB. Backup is running more than 20 Hrs and
still running not completed.
I would like to know.

Hi Team,
Any suggestion on tape backup?
Thank you,
Ankush

Yes. I recommend that you tune your database (mysql and postgresql
come with very poor default settings) and also increase the default
block size. 64K is way too small for a modern LTO tape drive.

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,
LTO 2…slow?

You may need to change memory settings for flushing, buffer sizes ...
Some distributions ship with mysql optimiz

Slow, but not as slow as mechanical disk drives.
What _seriously_ slows down backups is disk seeking (both on the client
array and on the spool disks), and tape drive will slow to a crawl if
not fed at near-full speed.
