System Volume Information ??????????

[cfdevlin01]

I was trying to perform my monthly clone of my 600 gig hard drive and discovered that my hard drive has gone from approximately 180 gig used space to 442 gig used space within the month of February. As a result the clone failed due to lack of space.
I checked the size of all folders on the C: Drive, but could not find nothing. Then downloaded and executed the free utility Folder-Size. The report showed what my problem is. SYSTEM VOLUME INFORMATION created seven (7) files during the month of February. Prior to that no file created since 2009, except one for System Restore in February 2013.

I have no idea what this is, or how to get rid of it. If this continues it will shortly blow out my 600 gig hard drive. My current used space in now 442 gig with 139 g free.

I noticed that twice the created files last month corresponded with my weekly Acronis True Image 2015 full incremental backup.

Details on System Volume Information are:
. Owner Unknown
. Attribute: HSA
. The last executions are:
. 2/14 - added 27.0 gig
. 2/13 - added 26.9 gig
. 2/28 - added 11.6 gig
. 2/26 - added 10.0 gig
. 2/27 - added 10.0 gig
. 2/20 - added 8.6 gig
. 2/19 - added 6.9 gig

I obviously need help in identifying what this is and how to get rid of it or correct something. I think I need to modify permissions in order to delete these files - that is as long as they can be deleted without causing any problems. Also how to prevent an on-going growth of these files. Thus - Help, Help

I think its creating Automatic system restore points.
and that's what is taking up your free space

I would try deleting some system restore and also reduce your system restore point size

Thanks for the info. I have done some research and realized the same. Tomorrow morning I will delete and resize. My question now is, why did this just start happening? Will need to monitor on an ongoing basis to see what may have changed to all of a sudden take up so much space.

yes I would start monitoring something big has to be happening on your system
to make dose system restore points

Just corrected the problem this morning. using the vssadmin list shadowstorage command saw that my maximum shadowstorage was set to unbounded. I deleted the system restore points which dropped my C drive space used from 445 gig down to 127 gig. Then reset maximum shadowstorage to 10 gig.

Interesting the way problem research and solution leads to knowledge.
