Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


What confuses me is that page:

http://mike.kruckenberg.com/archives/2006/05/mysql_backups_u.html

It states `LVM doesn't do a true online backup, although it gets close.'.

To me that reads `LVM is only capable of creating an "almost consistent" 
snapshot'.

Is that true?
