CentOS - Dec 2010 - "ultimate" backup choice

i have:
"SERVER A"
"SERVER B"

with "full root permisson" [ssh, etc]

each server has a folder.

i want to backup a folder in "SERVER A".

are there any backup methods, that meets these two requirements? :


1) running from e.g.: a cronjob

2) when running, it just checks the folder in "SERVER A" and
"SERVER B". if a file/folder has been added/removed/modified in the
"SERVER A"'s folder, then it copies/removes it/them to
"SERVER B"'s folder.

please help!

Thank you in advance! [for any links, howtos :\ ]

have a nice weekend

	Rsync will handle this situation perfectly.  "man rsync" for
	information and working examples.

rsync metts and exceeds the requirements

you can run rsync over ssh to secure the data transfer and rsync can transfer
only the "diff" of large files, to quote just two of the options you
have

Just google   backup using rsync    to access many howtos

For rsync over ssh see http://troy.jdmz.net/rsync/index.html or google   rsync
over ssh

I've been running BoxBackup on several servers and is quite satisfied.  Good
security and works flawlessly.  I'm mostly running them in "lazy
mode", which
means the backup daemon picks up changed files after a while and sends them to 
the backup server.  All backup clients uses SSL certificate so all data is 
transferred and stored encrypted on the server as well.

In addition to a neat simple "manual soft RAID" solution, where data
can be
spread over three directories.  I'm in the process now of setting up rsync
of
these directories to separate storages outside the building.  As if one of 
these directories are "lost" or stolen, the data makes no sense unless
you get
a copy of another directory to build up the third directory.  And considered 
each backup client uses separate encryption keys, the security is still good.

The only disadvantage I've found is that the restore features can be a bit 
cumbersome, and dates on directories are not preserved so well.  Windows 
client support exists, but if you have files bigger than 2GB, they need to be 
restored on a Linux box.

So nothing big and amazing, but slightly more advanced than rsync and simpler 
than Bacula or Amanda backup.


kind regards,

    Did you manage to implement the backup? Do let us know how it
went.<br>
    <br>
    FYI, rsync is a good choice because it is available on all popular
    distros and works fast in doing the backups. One advice is that you
    look out for differences in the trailing backslash for folders, as
    this impacts on what is being copied or created.<br>
