Hello to all PVE Users

I'm testing 2.3 rel and especially backup
so I noticed two things:

VM is on the LVM

- stopped machine
1. selecting lzo(fast) compression I got the archive size excatly the 
same as data quantity on the hdd
2. selecting gzip I got the same but more the 2 times slower backup

- running machine (selecting snapshot)
3. backup becomes 4-5 times slower ...  and the running VM slowes down 
too ...

It seems like there is no compression at all

It's impossible that 35G partition with 25G of data cannot be compressed 
at all ...

Is there any other switch that I can turn on in order to get compression ?

Please for the hint if possible ?

thank you very much in advance and

/srdačan pozdrav / best regards/
