system volume information files deletions

How can i delete my system volume information files, it is taking close to 500g of my exchange server, I'm already sys admin on the domain but i still can't delete it.

Also is it safe to delete system volume information files, since they are just restore points. Our exchange is on a VM and we take daily snapshots already.


thanks for the help

vssadmin resize shadowstorage /on=F: /For=F: /Maxsize=300GB

Doesn't reclaim 300GB it sets it to a MAXIMUM of 300GB,  you didn't recover 200G?

These may be exchange transactional logs

If they are the Exchange Transactional Log files, you need to be performing regular backups using an Exchange-aware software package.  If you don't have a 3rd-party system, NTBackup will work.  Each time you perform a backup of the Information Store, the Transactional Logs will be flushed (the ones already committed to the database).

Server 2008 backup is NOT exchange aware

Try
===============================
takeown /f "C:\System Volume Information" /R /A

then

cacls "C:\System Volume Information" /T /C /E /P Administrators:F

and now just delete it by a simple command

del "C:\System Volume Information\Sample File.txt"

If you want to delete entire folders then use

rd /s c:\folder  etc.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

you can use the disk cleanup wizard and/or go into control panel / system /System Protection / and change the settings there

or use vssadmin http://indrajitc.wordpress.com/2008/03/25/reclaiming-disk-space-from-system-volume-information/

sorry i have never used vssadmin before. And kinda confused what do do with that command.

And are the system volume files consider a shadow copy? I thought it was more of a system restore point. Also when i do look at the show copies in my computer management shared folders my shadow files looks good.

Yes shadow copies  are part of the svi .. not just system restore points.

please read the article that I linked to.

I have read the article but need a little bit of a guidance,

my current drive is F: that has the system Volume information.

it is currently 425gb with 46gb of free  and about 10gb of that is my log files for my exchange mailstores.

my question is when i run vssadmin what would my settings be? Will it erase all my data on that drive or will it erase only the sys vol info.

for example, will the below give me back 300gb of space?

vssadmin resize shadowstorage /on=F: /For=F: /Maxsize=300GB

thanks again for the help.

Cannot say. Back up your data first.

it will delete the older information (shadow copies/restore points) until it gets down to the size you configured

sirichaiphumiratAuthor Commented:
so this command will only delete shadow copies/restore points only? And no other data on that drive.

thanks for the help?
