Hi Arun,
Thanks for your elaborate mail. It helped a lot in learning more about
the backup solutions landscape.
In your place, I would encourage your "friend" to join such mailing
lists and forums and ask the questions directly, rather than use you
as a proxy.
We were discussing his problem and I found it interesting for many reasons
and I decided to dig little deep into it. Considering your advice,
I've asked him to join the group and follow this thread.
The best practice for storage/backup is "online" on fast storage NAS
or SAN, then close "inline" on slower disk storage or virtual disks
(tape) and finally on tapes (library). Which part of this spectrum
is your friend interested in?
I was thinking that there must exist an open source alternative for
Dropbox (except
the share feature), which can de-duplicate and compress data before
backing it up "online".
We have the same data replicated on multiple laptops. So it would be
redundant to
store the same data again-and-again.
My apologies if this looks like another requirement. In future I'll
post the requirements separately.
Take a look at amanda and bacula for "library" backup. They are cross
platform but I am not sure about OS X client.
Amanda serves most of our requirement. Digging into the source I could
see that it compresses and encrypts the data before transferring it to
the backup server. It also has plugins for uploading data directly to
some of the well known data-centers (Amazon S3 , Rackspace). But the
clients are closed-source. So if I'm using Amanda, We'll have to write
the clients (windows and OS X) ourself. My first impression of Bacula
is that it is not much different from Amanda, but I need to see the
source before I can judge.
Thanks,
dj
