Snapshots in Citrix XenServer. Sailed

As we know, XenServer 5.5 was released not so long ago, one of the killing-features of which was snapshots. All rejoiced - hooray, finally we can make backups of virtual machines without breaking their stops.
I was happy too. Upgraded I wrote a script that creates snapshots of all VMs and exports them to a remote server. I put it in the crown and it all worked. For a while…

And then one day I saw that everything broke. Backups do not work - a new snapshot cannot be created due to lack of space in the local storage.
Began to understand and stumbled upon forums.citrix.com/thread.jspa?messageID=1409941
I haven’t seen a more epic thread for a long time - a crowd of people ask Citrix employees - men, but where did the place go? To which they are calmly answered - his cellar zokhaval. Well, the snapshots work in such a way that they consume the tripled (!) Size of the virtual disk. And this is not a bug, this is a feature. Do not worry.
A number of speakers clarify that even this is not true - the place decreases in any case with each created and deleted snapshot. Others ask what they do now by spending $ 15k on an array of disks and a few more thousand on the XenServer license? Still others shyly specify how to return the place (so far to no avail).
Maybe there will be someone to solve this problem?
