Hi,

My system volume\dedup\chunkstore\{... }.ddp\data path has grwon to over 1 Ter.
How can u go about cleaning up or limiting the Amount of space that the sys vol is allowed to use?

i had already set a limit on the size which shadow copies can grow to as also re-directed the location of the shadow copy for the drive in question to another drive.

Hi Davis,

It seems i have a unique situation here.
i ran the garbage collection, but it changed nothing.

@David,
Certainly there must be a way to reduce the size of the chunk store.
It cant be a case where the chunk store is almost 4 times the size of the data that is stored on the disk.
It may; however, be running jobs on more than one volume!
