Seeking LTO / LTFS Wisdom.

[Neil Sadwelkar]

You do’t need to use LTFS ‘instead of’ Bru-PE since you can write and read LTFS from within Bru-PE too.
And, like Tim commented, Bru-PE uses CPU very lightly so most any tasks while Bru is running, is just fine.

Well, just a couple days ago when I was archiving, I opened PowerPoint, Word, Excel, and at some point my iMac was crashed badly. I had to press and hold the Power button to shutdown. After that, every time the archiving progress bar reached no more than 16%, the process stopped, than I couldn’t eject the attached external HDD or restart.

I use iMac 1.4GHz i5 dual-core 8GB RAM.

Hi Kiki,

As Paige related, the web master and the engineers had not connected on the 3.1.10 update and that why your download was the older 3.1.9.

However, the issue that you’re seeing is definitely indicative of an issue outside of BRU PE. Would you mind opening a ticket (if you haven’t) at support.bru.com so that our team can help you to determine what was causing the hang that you’re witnessing?

BRU … because it’s the RESTORE that matters!

Tim, I’ve opened a ticket and got answers from Eric. Will try the 3.1.10 tomorrow.

By the way, if I use a standalone HP machine, what’s the benefit of using unique volume serial numbers?

The proper identification of tapes is required to locate a tape that is needed for restore. With BRU products, you just need to now the file or folder(s) that you wish to restore, BRU will tell you which tape is required to perform the restore. If you don’t use unique identifiers, how would you know which tape will be needed? 🙂

[Jamie Watt] I figured out the relevant Terminal commands which did improve the speed of working with files on the LTO tape

Hi jamie, do you care to share the relevant commands? Right now I do it via finder, takes 5-6 hrs (same time if I use BRU PE) to finish archiving. Sure it helps me a lot if i could make the process speedier.

Thanks,
Kiki

If BRU PE is taking 5-6 hours to fill your LTO tape, something’s wrong and you should mention that in your support ticket. An LTO-6 tape with BRU PE should take just over 4 hours to fill.

Using the command line with LTFS simply removes the Finder overhead, so the performance there would be better than the Finder copy, but still slower than BRU PE.

Kiki,

Are you still following this thread? I’ve been in deep discussion with the folks at mLogic and we’ve got some ideas to solve both the performance and hang issues.
