Success

Yesterday, was a good day.

I received two packages I had been waiting for, one contained two pairs of shoes—one pair to wear and a set of spares. I love the Converse All-Stars, but I generally wear out the cloth at the heel in six months—and the other package had three LTO-5 tapes. I figured that would last a while.

This means I could finally do some write tests on the new drive, and it works perfectly.

It's kind of interesting to have terabytes of disk space available; I hadn't sized the disk for my dom0 in my system very big because how much would it need, after all? Now I needed some more disk space to install bacula so I just made a new lvm slice for /usr/pkg, problem solved. :-)

Once I remembered that the bacula SD (storage daemon) needs to be in the operator group, itwent swimmingly.

For reference, this is a backup of my data server with the old tape drive in my Alpha. It is an LTO-3 drive on a Ultra2 wide SCSI bus (80MByte/s), and the controller is on a 32-bit 33MHz PCI bus:

Job: BackupData.2019-02-09_17.33.18_08
Last Volume Bytes: 320,496,777,216 (320.4 GB)
Elapsed time: 9 hours 19 mins 23 secs

And on the new tape drive, LTO-5 on a 6Gbit/s SAS2 bus (via an expander) on a PCIe bus:

Job: BackupData.2019-04-04_20.39.05_21
Last Volume Bytes: 320,730,310,656 (320.7 GB)
Elapsed time: 1 hour 45 mins 51 secs

*chortle*

I am happy about that result.

For now I've kept the bacula director on the Alpha, but I'll move it soon as well.
