Don't forget that some of the value in Time Machine backups is to be
able to keep incremental backups over time. So if you have 200GB of
stuff on your drive and your backup drive is 350GB, that will be good
for your first backup and then Time Machine will continue to make hourly
incremental backups of anything that has changed. Depending on what you
are doing that can turn into a few GB per day. So how much you change
and how much space is left after the initial big backup determines how
far back in time you can go to retrieve stuff. If, as in my example, I
take some of that 150GB of free space and use it up for other stuff then
I decrease what Time Machine has to work with.

Hi Jonathan:
I think that I will back up on the same Hd and he same Partetion,
because my Hd is 400 GB, and my 2 hd for my mac mini and my MacBook
pro are only 350 GB, so I think shoud be ok, and most o them are
empty.
but just need to be sure that no interfere will be happened.
but my stratigy will be is to connect my External hd to my mac mini
and start the Tm, then connect my MacBook pro to my External Hd and
start the tm, is it ok, or do I miss something?

Hi ET:
THanks so much for the Carbon Copy Cloner advice, but, can I use it on
the same TIme machine Hd or seprat one?
don't worry about the size because, my Mac Hd is only 256 GB and I
don't store any files except my system and very very small files for
immediate work
so, do you trust the Carbon Copy Cloner? and will it do the trick
without losing data?

When I do time machine backups to a network drive I create a sparse
image on that drive so I can set the max size it will occupy, mount that
image and share the mounted image as my time machine backup drive for
another computer. I have this setup to store a couple TM backups to a
Mac Mini that has a single large drive for archives.

I have three systems with TimeMachine backups on one HD without using
a separate partition for each. One issue you might run into though is
I don't believe the automatic deletion of old backups works correctly
in this configuration. So as long as you have space on the drive you
should be OK. But when the partition starts to get tight you will need
to do manual deletions of the older backups as described last week on
this mailing list. If you want, you can even turn on Apple File
Sharing and mount the drive from one computer to another and then tell
Time Machine to backup to the Network partition. I haven't tried this
in the last two OS's but I believe it still works.
When you do the Network route, for some reason, the Macintosh creates
a disk image and saves your files to the disk image. I don't believe
this is of any concern, and I think the primary reason is to maintain
User Information and separate encryption availability for each
computer. .

With the partitions your single external hard drive should appear
on
your desktop as two drives. You'll have to decide how much space
to give
each partition. For example, if you have a 1TB drive you might
break it
up into two 500GB partitions. The main issue is that TM does
incremental
backups until whatever drive you give it is full. At that point it
prunes the oldest stuff to make room for newer stuff. In that way,
how
far back in time you can go depends on how big the drive is
relative to
how much stuff you need to back up. If you did back up both
machines to
a single large partition it probably would work for a while but
eventually one backup would start getting starved for space as the
other
used up space. Basically you would have two greedy processes not
sharing
well together on the same drive. I have seen tricks where you use
disk
utility to create a sparse image on the drive, mount that sparse
image
and backup to that. The sparse image can has a cap set on how large
it
can get so it would act like a partition, but at that point it
might be
just as easy to make an actual partition.
