A very worthy suggestion thank you, though I have no idea of the
capacity of this particular server - I believe it currently has a 12 x
1Gb drive 10 RAID array.

Still doesn't overcome the issue with 'local' storage for backups (if
you aren't fully aware of the issues with lvm-thin)

I still think that for at least single server installs lvm-thin is not
necessarily the best default option, and there should possibly be more
warning for some to RTFM before hitting go for a default install.

(Note this was not my server and I was not involved in the setup - I was
just asked to look in later when the damage was already done ! On my own
servers I had purposely chosen not to use lvm-thin after reading about it)

I did notice a number of posts in the forums where people were
struggling with similar issues, so clearly I'm not alone in these thoughts.

Many thanks for all your suggestions and a great product nonetheless
(and I am a paying supporter :-) )
