The 4 files in the root (or top) directory of the SD Card change daily (according to their time stamp) so I copy and replace each of those files daily. The 32 files in the SETTINGS directory also change daily so I also copy and replace them daily. The files in the root directory and the SETTINGS directory are not necessary to copy each day as they are summary files or configuration files and are changed daily by the S9.
The Files in the DATALOG directory are added to each day and I copy the new files daily. If you are not doing daily copies you want to copy the file you have not copied before. My goal is to have and retain all of the high flow or high sample rate data as well as the low sample rate data. The ResMed S9 removes the _BRP.edf data files (high sample rate data) that are older then 7 days and removes all the low flow data (_PLD.edf), event data (_EVE.edf) and oximeter data (_SAD.edf) after 30 days on the SD Card. What this means is that if you want to keep the high sample rate data files you must copy them at least every 7 days or else they are gone.
Hopefully I've answered some of your questions but if I've missed anything or need to clarify something feel free to ask.
I'm attaching an image of my computer screen that shows ResScan's Import screen, where I used the browsing feature of ResScan's Import function to go to the ResScanSDCard
folder on my computer's hard drive.
By way of explanation, the screen shot of where I browsed to in ResScan's Import functionshows the DATALOG and SETTINGS folders that I copied from the SD data card from last night's (12/26/13)use of the S9 Auto Set. Surprising to me,
I don't see the 4 files you said needed to be copied each cay! ! ! If you look at the two attachments you'll see that the 4 files do, indeed, appear on my computer in the ResScanSDCard folder; however, they do not in the screen shot where I used ResScan's Import function!
However, they are included in the below framework I use for all my backups of any data; so, maybe I could just highlight one of the dated folders because under them are the 4 files?
Referring to the screen shot attachment:
The folder named ResScanSDCard122413
contains the DATALOG
, and 4 files
from my sleep on 12/24/13--as well as my sleep from 12/19/13 through 12/24/13!
The folder named [b]ResScanSDCard12/26/13
contains the DATALOG, SETTINGS, and 4 files I copied from last night's (12/26/13) SD data card and pasted into the named folder. I would expect they would contain data from 12/20/13 through 12/26/13.
[More on this below, since 12/19/13 "probably" isn't included, and I'm too chicken to test it without being able to successfully import ANY backups, yet!]
Check me out on this, if I can only highlight one item, and I want to make sure I get the high resolution data beginning on 12/19/13
(my first day's import into ResScan), would I not choose ResScan1224
13. That would capture the everything from the 12/19/13 night.
However, if I highlighted ResScanSDCard1226
13, I would lose 12/19/13 high resolution data because last night was the 8th day
I imported data into ResScan!
That would seem to be true because RedMed puts out the information that the high resolution data is deleted after 7 days.
At some point, once I am successful in importing ANY backup data into ResScan (rather than just using ResScan's Import function to import straight from the SD Card), I guess I could try it, but I'm afraid to import ANY further data from the SD Card! ! !
Am I correct in all the above, and the bottom line is that I just do the following:
1) highlight ResScanSDCard1224
13, and I would then be looking at detailed data in ResScan from 12/19/13 through 12/24/13?
2) highlight ResScanSDCard12/26
/13 and import it if I wanted to look at data from the night of 12/26/13!
Finally, if all the above is
to funny to be true, what exactly should I do at this point.
P.S. I still have questions about why only copy the "last/latest 8 files" in the DATALOG folder, but that for another day, unless importing anything from my screen shot won't work.
