Unless the filesystem is very busy, you will get your data backed up. 
If you have things like databases, I still would not trust 
snapshots.  Better to use pg_dump or mysqldump or the app that comes 
with whatever DB you are using... When backing up things like / and 
/usr, I would hazard a guess that most things are not changing while 
the backup is running, at least they dont in my environments.  I have 
never had a problem with things like /home and even /var or /mail 
which are changing quite a bit.  We dont restore much in the course 
of our daily routine, but we have always been able to restore 
people's Maildir when they accidentally have deleted stuff and it all 
worked without issue over the years.
