I'm trying Windows Server Backup, and it's doing incremental backup in order to save disk space.
it's working greate, but now I have 36 copies (1 is full backup, others are incremental changes since the full). is there any way to keep only last 30 days backup? or it's impossible for this kind of backup

Not possible with the way you're doing it. You need all the incremental backups since your last full if you want to be able to restore.
If you want to purge your incrementals more frequently, you need to do a full backup, then purge the older backups.
And, incidentally, it doesn't sound like you have a good backup strategy. Backups are really only useful if you have some level of retention on them. What happens if/when you find out that someone deleted an important file/your server got hacked/your filesystem got corrupted 3 months ago? If you're only keeping backups from the last month, you're screwed, is what.
Also, I sincerely hope you're not keeping these backups on the same disk(s) as are running the server, because if you are, they're not really backups.
