All
I have decided I really ought to do something about backups, the old
system of copying everything to a CD every so often that has worked for
years is showing its age.
So I bought a 1T drive, and formatted it ext4, it shows up as 1000gig free.
So I copied /home off an old machine on to it, this lists as 159,323
items totalling 28.4GB, and now the drive is showing 899GB free.
Does everyone just ignore this, and buy bigger drives?
If I partition it up how many partitions do I need to make it worth the
effort.
And as the idea is to copy several machines and some old drives on to
one drive (all eggs in one basket ) has anyone used any deduping
software for home use.

Using smaller partition sizes to get smaller cluster sizes is a
Microsoft-ism.
Linux extX filesystems reserve some blocks (default 5%) for root. If you
didn't override this, that probably explains the discrepancy. To check, run
as root:
# tune2fs -l /dev/sdX | grep Reserved
Finally, there's also the difference in definitions between binary and
decimal multiples; OSs usually use the former, storage vendors the latter
(<http://en.wikipedia.org/wiki/IEEE_1541>).
HTH,
Alex

Even more confused, if it is reserved by the format, why did it show up
as free before the copy. Ubuntu has joined the binary is too difficult
for users brigade, it listed it as 1T free = 1000.4GB.
Reserved block count: 12209500
Block size: 4096
So 28GB + 48GB + 899 = 25missing. I guess I stop worrying there. And
only ask for the reserved back if I get too full.
Thanks

Hi David,
As regards deduping software I've found dupeguru pretty good and the
developer has recently opened up the source. You can find it here :
http://www.hardcoded.net/dupeguru/
Cheers,
Adrian

Hi everyone, just joined the mailing list and thought I'd introduce myself.
My name is Adrian Portway, I'm based in Chard. Been using Linux for about
10 years or so starting with Mandrake 9 on an old Dell Inspiron laptop.
I work as IT Manager at a firm in Devon looking after the desktops ( mostly
Windows ) and servers ( all Linux ).
Hopefully I'll be able to get up to Bristol to meet a few of you some time.
Cheers,
Adrian

Hi,
Welcome aboard,
As an off topic, I will be back in Bristol in June ( 24th ) until July
14th, I was hoping to meet up with everyone. Can someone point out if
there is a meeting within that scope?.
Living in Florida leaves me with a rather hefty mileage deficit.
Regards
Nige
