How to Change the System Restore Disk Space Usage Amount in Vista

| | How to Change the System Restore Disk Space Usage Amount in Vista Information | | By default Vista allocates 15% of your selected hard drive volume to storing System Restore points after installation. If System Restore is turned on much later, it may only allocate a minimum of 30% of the available free space instead. When the allocated space fills up with restore points, System Restore will delete the older restore points to make room for the new ones. System Restore needs at least 300 MB allocated to it to run, and will not run on a hard drive smaller than 1 GB. In the Vista Business and Ultimate versions, this area is also where backup copies of deleted or changed files are stored and made available through the Previous Versions feature (Shadow Copy). For more information about the Vssadmin command, see: Microsoft Technet: Vssadmin |  | WARNING | | - If you shrink the available storage space for a selected drive, Vista will kick out the system restore points and backups on a first-in, first-out basis. The oldest restore point will be deleted as the new one is saved when out of available max space. This will, of course, leave you with fewer restore options.
- If you dual boot with Windows XP, then everytime you start in XP the System Restore Points and all except the most recent Complete PC Backup files in Vista get deleted. For how, see: How to Stop System Restore Points from being Deleted in Vista when Dual Booting with XP
|  | Tip | | If you just want to free up some space, then you can run Disk Cleanup instead. |  | RELATED LINKS: | STEP ONE: |

| How to See the Current Allocated System Restore Size |
1. Open a elevated command prompt. 2. Click on Continue in the UAC prompt. 3. In the elevated command prompt, type vssadmin list shadowstorage and press Enter. (See screenshots below) NOTE: This will give your the details on the Used, Allocated, and Maximum spaces of Shadow Copies for the available disks that you selected to have restore points created for in step 6 here: How to Turn System Restore On or Off in Vista . The left screenshot is for just one drive selected, and the right screenshot is for two drives (C & D ) selected.  | STEP TWO: |

| How to Change the Maximum System Restore Size |
1. In same elevated command prompt window from above, type for EX: WARNING: If you change the MAX size to a smaller size than the current Used size shown in METHOD ONE above, then the older restore points will be deleted to adjust to the new size. Nothing will happen to the restore points if you make the MAX size larger than the current Used size shown in METHOD ONE above.A) For the listed C: drive: vssadmin Resize ShadowStorage /For=C: /On=C: /Maxsize=3GB and press Enter.
B) For the listed D: drive: vssadmin Resize ShadowStorage /For=D: /On=D: /Maxsize=3GB and press Enter. NOTE | |
See the screenshots below step 5 in OPTION ONE above under the Shadow Copy Storage association line for each drive listed. | Command | Description |

| /For= | The For volume: listed. (Ex: C or D above) | | /On= | The Shadow Copy Storage volume: listed. (Ex: C or D above) | | /Maxsize= | What you want to limit the maximum storage size of Shadow Copies (restore points) to. For example, # + GB or MB (Ex: 3GB or 3MB) This must be 1MB or larger. | |  | 2. You will get a Successfully resized the shadow copy storage association 3. If not, repeat step 1. 4. If yes, then check with STEP ONE above to confirm the change for the selected drive. 5. Close the elevated command prompt when done.

 | Wow.......when I ran this command, the maxsize was 15.779 gigs. That's a lot of space for System Restore.
Read something like this:
Used = 286 mgs.
Allocated = 700 mgs.
Max Size = 15.779 gigs
Re-sized max size to 3 gigs.
Thanks for that tip.
Also......question:
Was wondering why 're-size SR' is basically hidden in Vista? XP and previous versions have all had the slider for re-sizing space used, making it very simple. | My System Specs | | OS Vista CPU Q9550 Motherboard EVGA 790i Ultra Memory 4 gigs Patriot Viper EP @ 1600mhz Graphics Card EVGA GTX 280 Sound Card X-Fi Fatality Pro Monitor(s) Displays Samsung 2493 24" Screen Resolution 1900 x 1200 Keyboard Saitek Eclipse 2 Mouse Logitech G5 Laser PSU PC Power & Cooling Silencer 750w Quad SLI Case Antec 900 Cooling Asus Silent Knight 2 CPU Hard Drives WD 640g SATA 3.0 16 AAKS Internet Speed Now @ 15mps down

It was an effort in dummy proofing Vista. In actuality, it made it harder on advanced users. Vista can use a lot of space on System Restore. If you have a big hard drive, I suppose one could afford the space.

 | Re: System Restore - disk space I have my Vista computer for a month and already have 17 GB used for restore points. I am very surprised how quickly my 160 GB drive is filling up. I only have about 1/3 of that free. What is a reasonable size for a restore point allocation. How may restore points does Vista keep before it begins to eliminate some? | My System Specs | | OS Vista Home Premium 32 Bit

System Restore needs a minimum 300 MB of space for restore points. By default it is set to use 15 % maximum of your hard drive. When that runs out, it will then start deleting the oldest restore points one by one as new ones are added.
I would give it a 3 GB size to have room for enough restore points and shadow copies to be safe with multiple one to choose from.

 | Re: System Restore - disk space So the restore point allocation is 15% of 160 GB in my case? I think my report says 21+ GB is the maximum. They must be using the 141 GB they show for that partition where the 7 or 8 GB recovery partition and something else takes up the short fall from 160 GB. What is using up the other 11 or 12 GB? I will try the 3 GB you recommended and expanded it only if I make a major change in applications used. | My System Specs | | OS Vista Home Premium 32 Bit

If you had System Restore off, then turned it on later it may allocate a minimum of 30% of the available free space on the hard drive.

 | Re: System Restore - disk space After I change my restore allocation is Vista likely to change the allocation without my knowing it or will Vista give me a warning if it has less allocated space than needed for setting a restore point?
I have an HP dv6449 with Vista Home Premium and the recovery sector is thought to be corrupted. I couldn't create a recovery set so HP sent me a recovery DVD. That 7 or 8 GB partition is not very useful unless I can easily put it in the primary Vista boot partition or use it for data or restore points. Is the latter possible? Does Vista Home Premium have disk image software? | My System Specs | | OS Vista Home Premium 32 Bit

Q1) If you turn System Restore off, it will reset back to it's default maximum size when you turn it back on the next time without any notice. Otherwise, it should not change without your assistance.
Q2) HP may have that partition protected. If they do, then you will only be able to get rid of it the next time you reinstall. During the installation process you can delete all partitions and create one big instead. If it is not protected, then this will show you how to delete it and extend the other partition into it to make one partition on the drive.
