CPAP Data Recovered

As I may or may not have mentioned, Zen failed to boot after it got the latest set of Microsoft patches on February 15th. After various attempts to recover, it has been declared lost. I haven't gotten around to resurrecting it.

So, I've been making do with a Windows XP VirtualBox that I have my on Linux system (starting to look like when I do get around to resurrecting it, I'm going to try 12.04LTS Desktop and Windows 7 in VirtualBox....)

Previously, it was just Quicken and then TurboTax. But, I've been wondering about my CPAP data.

First was EncoreViewer. How do I recover that historical data. I knew where it kept the files, because I had copied them from TARDIS into Windows XP mode. The question now was how do I get the files out of Windows XP mode. In the end, the answer was WinImage...to merge the differencing-VHD that Windows XP Mode uses, into a single file and then convert it for VirtualBox use. Could've gone direct...except that I found first try with WinImage didn't work...so second time I converted to a fixed VMDK file, and then converted the fixed file into a dynamic sizing virtual disk for use on VirtualBox.

Though later I realized that I only want it as read-only....to get my data back....anyways.

That worked.

Next question was how do I recover my data in SmartLink.

I installed it into my Windows XP VirtualBox, and wondered where does C:\ProgramData exist in Windows XP space....but, while poking around, I remembered it has a backup/restore database option...and wondered if I had ever done a backup.

I lucked out. The last time I used the software was the only time I had ever used the backup function....and that's just perfect, I restored from that and then did my latest downloads from both my xPAPs.

:cool:

Just have to see if I remember to do another download before my next doctor appointment. I didn't print anything, because I hope that by then...I'll also have my new printer. :))

Morning Orac outage

Well, Orac was being somewhat unresponsive this morning.... Looks like early this morning the system stopped answering to Cacti, with the temperature of the GPU rising to a new high. Don't know what the high would've been, because there was no snmp data for a while. GPU temp did recover, but the display did not.

Ended up rebooting, needed the excuse to see external journal work....

Once backup, I switched back to internal journal...but one of maximum size rather than default size. And, then shutdown the system to extract the PCI Compact Flash card. During the reboot to see external journal work...I realized that I wasn't likely to see much performance gain from getting faster compact flash since the card itself was only UDMA/66. So the 133x CF is already faster than the card?

Probably should've fsck'd manually after the switch back....some discussion thread suggested doing this after fiddling with journal settings. But, its fsck'ng now after the boot back up. Apparently superblock had invalid external journal superblock hint? And, auto fsck failed, requiring manual fsck.

Downside of internal journal is that it can only be a max of 400MB (an improvement from the 128MB default I had before)...but that's only like 0.01% of my total space. And, there was a discussion thread that seemed to suggest a journal size of 0.2% would yield better improvement....I didn't do the whole 16GB CF card...though wonder how much that would've helped.... But 0.2% would call for a journal of ~10.9GB. Suppose I could turn off data journaling, especially since there are files that backuppc puts down that are bigger than the 400MB journal. Though I think the ordered/writeback modes usually just do metadata journaling, while I had switched it to data journaling when I was playing with external journals...but I didn't switch it back.

Wonder which of writeback or ordered would be more optimal for this FS? :??:

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
