hello,
here's the story :
on the 25th avast created 2 restore points (I had been fiddling with avast)
on the 27th, avast updated and created 2 more restore points - so I had 4
today, 28th, window update created a restore point... but why did all the previous ones disappear ?
I just do not understand !
thanks for any light !
Think has to do with the allocated amount you set for system restore. You can raise or lower the amount. System Protection - Change Disk Space Usage
Restore points are stored in the shadowstorage. The space is used with a FiFo algorithm (first in, first out.). Each restore point takes about 500MB to 1GB. If e.g. you have only 3GB of shadowstorage, chances are that no more than 5 or 6 restore points can be stored and the oldest ones will always been thrown out to make room for the most recent. You can allocate shadowstorage with this command:
vssadmin resize shadowstorage /For=C: /On=C: /MaxSize=10GB
The 10GB is just an example. You can chose any size that fits on your disk.
But that's not what happened in this case.
When the April 28 restore point was made, the oldest restore point was NOT thrown out--dating back to Feb.
Instead, the two restore points from April 25 were thrown out. The older restore points from Feb and March were kept.
Maybe Windows does not treat restore points made by Avast in the same way as restore points made by Windows?
That's what I'm suspecting; System Restore Manager from Windows Club seems to bear this out, in an indirect way....Maybe Windows does not treat restore points made by Avast in the same way as restore points made by Windows?
Why would Windows 7 care about restore points made by a 3rd party program?
Windows 7 cares about Windows 7 and it's ways and methods.
hi !
thanks for all the input
the allocated amount was way above the current use, so too little storage space is not the answer
all the dates listed as "system image restore point" correspond to my back ups, these are made on an other drive... or do those back ups also store something on the C drive ?
do any of you know ?
on an other thread, someone suggested I disable avast secure virtual machine
immediately after I did, the current use dropped from over 25 GB to less than 6 GB without any restore point vanishing - I was happy !!!
but it did not last, the used space is again very erratically going up and down, I just have no idea why...
there is a suspicion avast is the culprit
have to find the avast forum
Correct. Avast has been known to cause this problem.
Take a look here.
the dwindling free space on my C

Why would you stay with something you yourself define as a "real pain", particularly when you can go back to it if and when the developers ever sober up and provide a fix?
