Small business server 2011 - Dynamic VHD growing out of hand

hello!

recently have been experiencing strange growth in our vhd files our sbs 2011.

the settings this:

the sbs has c-drive assigned dynamic vhd file. d drive static vhd.

some months ago server not start due no space left on partition host keeping vhd files. had run disk compact. solved our problem.

now here problem:

even though sbs c-disk has used 50gb, of total space of 150gb, vhd file 175gb big.. , still growing, everyday.. disk compact feature won't shrink down normal size anymore, gets bigger , bigger.

i tryed uninstall our anti-virus on server, reduced growth still getting bigger.

any suggestions on how solve this? :)

hi,
first, it's recommended use fixed vhd in production environment.
anyway, try explain:
1- problem encountering dynamic vhd grows don't reduce automatically. dynamic vhd can  growth maximum size (127 gb default).
2- when data inserted vhd, size increases. when data removed vhd, vhd keep size. guess, in given time, vhd has increased 150 gb, after this, data removed vhd stay @ 50 gb.
3- reduce used volume have to:
    1- sbs machine, go server manager, storage, right click c: drive , choose shrink
    2- choose size want shrink (select max if want reduce maximum)
    3- after shrink process, can use compact tool compact vhd.
