Hi!
Running 2012r2 file server.
How can I increase the number of shadow copies? Currently I can go back only three days. Shadow copies taken at 09:00 and 15:00. 4.6GB Used for shadow copies, I have defined maximum size "use limit: 102400MB" for shadows.

Hi,
The maximum number of software shadow copies for each volume is 512. However, by default you can only maintain 64 shadow copies that are used by the Shadow Copies of Shared Folders feature. For more information to how to change this limitation, see the following article

Besides, please check if there's enough space. If after the MaxShadowCopies value is set, you still couldn't create more shadow copies. Could you test to try to choose No limit in Maximum size of Shadow Copies and see if more snapshots could be created. You could also manually create snapshots for testing.

Hi!
I already had set HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VSS\Settings\MaxShadowCopies 256. I changed it now to 512 and rebooted, it seems that the amount of the restore points is now increasing.
