Re: [Hampshire] Recommendation please - Big NAS
With two drives you can double your storage, but halve you MTBF (mean tme between failure), or effectively double your MTBF for the original capacity (RAID 0 vs RAID1). LVM across two disks has essentially the same problem as RAID0 in this case. I would seriously think about 3 drives and RAID 5, which will give you sufficient capacity with a degree of redundancy, all mounted at a single mount- point. Tim B.

[Hampshire] rsync 101
Hi all I need a bit of help with rsync (well grsync actually but I assume grsync is just an interface to rsync) please... What I've used it for in the past is to mirror two drives - and it works fine. However I've noticed the following and I need a workaround. Let A be the master and B be the backup. If A contains: /foo/bar/fred Say I've backed up A to be before such that B now also contains /foo/bar/fred Now let's suppose that I make a change to A so that it is now /foo/bar/1987/fred (and fred is still the same file). Running grsync in the usual way means I end up with /foo/bar/1987/fred (which is correct) but I also end up with /foo/bar/fred (which is now a duplicate - and can be deleted) What I want grsync to do is ensure B is a direct copy of A. I'd prefer not to do this via taking an image (because A and B are retail USB 2TB drives and have some form of windows utility (which comes back after formatting no matter what fs I choose) on them and the last thing I need is to render them unusable). I suspect it's just a switch I need to set but I can't find it immediately - so any help very well received.

I assume there's some way to specify rsync options with grsync, but I'm afraid I've never used it.

Re: [Hampshire] rsync 101
> but I also end up with > > /foo/bar/fred (which is now a duplicate - and can be > deleted) You're looking to add one of the --delete options to rsync. I've no idea how to do that in grsync - I don't use it. The exact incantation to use depends on when you want the deletion to occur - have a look at the man page for more detail.
