LVM is a dandy tool, especially after having juggled partitions trying to
shoehorn stuff on my not-so-large HDs. Unfortunately, it is a layer between
the usual data tools and the data.
What is needed is a LVM data/directory mapping tool that can be niced away and
croned. Some way of extracting data "raw" from LVM volumes could be devised
based on this map, I think.
Backups? Should be done. Unfortunately, not always possible without contiguous
space for intermediate storage for the backup medium, i.e. 4gig for a DVD.
Offsite backups are crippled by upload speed limitations of internet
providers. One must simply spring for that multi-terra USB or NAT and hope the
job ever finishes.
