Slow restore speed from rescue CD
I'm currently restoring my PC using B&R v10.0.11345 across the network from a file share. It's restoring at ~4.5MB/s which seems rather slow. It is a ~40GB restore but I'm sure when I've restored using TI in the past, the restore time has been way less than an hour.
What speeds to other people get? This is over a 100MBit/s PoE switch on a four year old Dell Dimension 5000.
Cheers, Rob.
PS. Is there a newer version out yet?
And answering my own question about a newer version, the answer is "No". As of 8th April 2010, it's still v10.0.11345 which was released over four months ago. Four months, hundreds of bug reports and still no new release. Hmm...

Later #1 - currently validating the image is okay using another instance of B&R on another PC and this is validating at a much more reasonable 35MB/s. However, I don't know whether validate actually reads all the data. This is from within Windows 7 on 1Gbit NIC whereas the original message was talking about restore from Linux CD on 100Mbit NIC.
Later #2 - oh for *(&(*&(*&(&(* sake... the verify on this other PC finished I think but I'd made the mistake of keeping the progress window open and now it won't close. Had to manually end the task. Running again but without the verify window and if I have to type in the network credentials one more time, I'll scream!
Later #3 - verify without progress window and it reported another error on validation. But B&R crashed again, I think trying to display the log window. End task again and look at log on restart. Hmm, maybe I got the logon credentials wrong (did I say I was bored with entering them?) so that could have been why it didn't verify. Still B&R shouldn't crash trying to display the log.
Later #4 - discovered that the task information dialog is displaying but getting it into focus on Windows 7 is a game of cat and mouse. You can get it into focus by hovering over the task bar and right-clicking the window.
Later #5 - but completely given up trying to right-click in Windows and validate vault. Just won't run - problems with authentication. Manually started the task from within B&R and it's currently running. So another bug - validation from Windows Explorer is broken
But some good news in the middle of all of this, I'd left the original two hour restore running and this time is finished without some weird error... After five hours, the PC is restored to an earlier image which is all I wanted to do.
And for some reason, the verify ran perfectly the second time and the information dialog popped up, in focus without error.
It's this unpredictable behaviour that's so worrying...
But original question still remains - isn't a restore speed of around 5MB/s (it crept upt 7.6MB/s) much slower than expected?
