Anyone figured out the disappearing restore points problem

  1. #71


    Here's my progress report:

    I'm still unable to verify that the way the system is originally set up, an automatic RP is created after 7 days of no other restore point being created. Every time I got close to 7 days, I'd do something (like install a program) that would add a restore point, so still no 7 day dry spell.

    I'm still watching the used space growing by about 2 GB a day, however, I increased the allocated space to 4%, about 36 GB. This morning with 4 restore points, the used space got close to the allocated space, and knocked out the oldest restore point from 4/17. So I've gone 17 days before I lost a restore point. After the oldest restore point was dropped, the usage went down to 22 GB. It should take another 6 days before I lose another RP, by then I should have an automatic RP added. I think what I'll see is that 36 GB will let me retain 3 - 4 restore points.

    JeffL, although I don't see much point in verifying the 7 day span apart from curiosity, the easiest way is to install Windows on a virtual machine. There you can turn off windows update, delete RPs in the system protection options and run a scheduled task that creates RPs twice. The first time it should create an RP, but not the second time. Turn off the machine and run the scheduled task in 7 days.

    For figuring out the "RP count / space" ratio, you need to experiment on your main system, because it depends on the volume of files covered by RP (this includes your personal files as well). Just keep creating RPs manually from the control panel until the oldest RP disappears from the list. (strike-through explained below)

    Vadikan- I'm trying to verify the 7 day waiting period, because I've seen so many posts from people that say they are not getting automatic updates.

    Regarding your test for RPs per allocated space, my experience has shown that that wouldn't work, because the oldest restore points have not been falling off of the list until the displayed used gets space gets close to the allocated space, and no matter how many RPs I've had at one time, the displayed used space (from a clean start) is only increasing at 2 GB a day, instead of appearing all at once for the total amount of space needed for the RP. I think that was the basis of my original post.

    That's correct. When where's not enough space in shadow copies to save the next restore point, the oldest point gets deleted. You control the space in the system protection options.

    In the hindsight, my suggestion to create a bunch of points would be an inaccurate experiment. Shadow copies are incremental, so if there are no changes to the files covered by system protection, the space used by restore points won't grow by much.

    This also means that there's no exact or even approximate figure for the amount of space taken by a single restore point. It all depends on the total volume of covered files as well the as on how much they change between snapshots. It could be 2GB for you or 250MB for someone with a tablet used for web surfing

    So, one of the problems is that the System Volume Information folder keeps increasing with size despite vanishing restore points?

    I just checked this system, my Reseved area is 14 and a half Gigs, and right now there is 7 and a half gigs of that being used: and eight available restore points. Does this sound right?

    My guess on the machines which seem to be gobbling up the reserved area, that the earlier points are actually still there, but not being shown. This was indeed happening to me on the machine that was monitoring three drives, Four if my My Book was attached. Once I set System Restore to only maintain one drive, that all stopped.

    I don't see how this is possible. Don't forget about the earlier restore points checkbox in rstrui.

    If you want to get another view, run in the command prompt
    Code:
    vssadmin list shadows
    Compare the dates of shadow copies with RP dates in rstrui, and you'll see the match.

    Again, this doesn't sound right. Shadow copies are saved per volume. This means that RPs from drive C are saved on drive C, RPs from drive D are saved on drive D. The above command shows that precisely.

    System protection is not a black box, although posts in this thread kind of give this impression

    Not quite. Using the language you would see if you run VSSADMIN LIST SHADOWSTORAGE, my "Used Shadow Copy Storage space" increases at the rate of about 2GB a day. Once it gets close to the "Maximum Shadow Copy Storage space" (which is the amount you set by choosing a percentage), the oldest restore point goes away, and the amount of "Used Shadow Copy Storage space" goes back down (and starts growing again).

    In the example I posted a few posts back, I had 4 restore points. The oldest dated 4/17, the newest dated 4/20. When my used space (growing at 2GB/day) grew close to my max space (36 GB), the 4/17 RP fell off the list, and the used space went back to around 22 GB. Right now, it's grown back to 23.3 GB, but it will keep growing.

    I would have thought that when the newest RP was added on 4/20, the RP from 4/17 would have fallen of the list right away, but that isn't what happens. I could add many more RPs, but the oldest ones don't go away until they are pushed off the list by the slow growing "Used Shadow Copy Storage space" number getting close to the Max space number.

    I know the last part does not sound right, but in my case, the affected machine is not exactly running the OS from only one drive, it's spanned across all of the installed drives. I can boot from all three drives and it opens up the Windows 8 OS choice menu. My other machine, it'a all on one drive.

    I don't know how or why that happened, but that is the case on my Media Machine - if I remove any of the drives, it will not boot. They all have to be there. There is something in my Event Viewer that refers to a "JBOD" array. I have Windows 7 on one drive when I choose it, it reboots, when it comes back up it is the old dos Boot Options menu, from there I can boot to 7. the Windows 7 drive is the first one in the chain, and it is the only IDE drive in the system, the rest are SATA.

    On this machine here, if I choose the D drive from the BIOS, it boots straight to Windows 7.

    I don't even know if there is a way I can print up a system report and show you, and its been bothering me ever since I installed 8 on that machine.

    Finally! I have the proof that it works the way Microsoft said it works in Windows 8. After 7 days of no new restore points being created, an automatic restore point was created. I checked my shadow storage usage before and after the RP was created, and there was not a significant increase, it just continues its steady growth at about 2 GB a day. It's at about 26GB right now with 36GB allocated, so if I don't increase my allocated space, I should see the oldest RP fall off the list in 4 to 5 days, leaving me 3 restore points, and a new restore automatic restore point created a few days after that giving me 4 again. Of course as I start using more disk space, more space will be needed for RP shadow storage.
    Whoomp! There It Is:

    I just checked mine - My Usage DROPPED to 6.8 Gig from, 7 and a half gig with 14 and a half total. But my very oldest restore point has vanished- But Evernote installed an update which created a new restore point.
