Space taken by snapshots can be found during a mirror copy it seems ?

Hi,

I found the following information during a mirror copy

dfly-bkpsrv# hammer mirror-copy /Backup1/www-5mbak/www-hot /Backup2/pfs/www-hot
Prescan to break up bulk transfer
Prescan 1 chunks, total 3697 MBytes (3876851752)
Mirror-read /Backup1/www-5mbak/www-hot succeeded

So I did

dfly-bkpsrv# cd /Backup1/www-5mbak/www-hot/
dfly-bkpsrv# du -sh
3.2G


3.2 GB * 1 024 = 3 276.8 MB

So the space taken by snapshots is

3697 - 3276.8 = 420.2 MB

right?

Thanks :-)
