Greetings,
I have a USB external 2TB HDD with one NTFS partition which is to be used for backup up from about 5-8 workstations (all Win*) all are shut down when the office is closed
I am playing around with Amanda server on Centos 5.7.
(It is over 3 years since I last implemented Amanda for about 50 workstations mostly Fedora and couple of XP boxes -- it sang and danced quite nicely.)
Now the issue I have is: 1. I want the External HDD to appear at another mountpoint than the /media/<HDDLabel> persistantly on the centos box.. 2. How do I ensure that amanda starts and completes its backup say between 0800hrs and 1900hrs. (/ducks -- I _know_ it is amanda related, I am crosing my fingers here) 3. Is Amanda really a good choice or an overkill in this scenario, given that this is a small s/w development shop where linux expertise is *not* available? 4. Is there an alternate simpler automatic network backup? (Bacula too seems overkill) 5. Amanda is in its 3.x avatar ("The most recent stable release is version 3.3.0"). Whereas Centos 5.x yum install yeilded (I dont know from where) amanda-server-2.5.0p2-8.el5 which -- as is usually expected -- a bit dated 6. The Windows client is 3.1.3. Will the ancient server and shining new client play nicely? 7. Is there a howto using rsync/rdiff given that Windows Scheduler is not exactly like our trusty, mature cron.
The centos wiki on this matter is, well, a tad old.
Surely the Centos server, which I introduced, in this shop is going to stay and will not go away.
Of course RDIFF and other things are valid provided I have another Centos box.
Any answers appreciated.
TIA

Look at backuppc. It has a nice web interface to manage it and browse/restore backups and it compresses and pools identical content to hold much more online than you would expect. It is all controlled from the linux side and can work with windows either over smb or you can install cygwin rsync to save bandwidth. You would want to format the drive with a linux filesystem, though.

Thanks a million for that!
You would want to format the drive with a linux filesystem, though.
Now, that is a typical dilemma that any sysadmin (a lowly and not so respected Job in India), and I can't do that that is a constraint as this external HDD is supposed to be connected for recovery on a (horror of horrors! - winx node in case the centos node fails -- nevermind the neat li'l tar format -- coz everybody in this scenario is afraid of Centos. Well gimme a week. I have at least one Centos box [the elephant in the china shop] to fight with and turn them around :) )
With warm regards and best wishes,
Rajagopal

BTW, how may persondays it would require on a Centos 5.7 box to master? I have squandered away about 75% of available time (of about 2 person days). Amanda, IMHO, requires about 1 person week to deploy initially and about 2 person weeks to get sign-off: am I right about it? or am I inefficient (the "in about 15-minute" is a myth with Centos 5.x maybe truth with Centos 6 -- I dunno)?
There is a External NTFS partition which will be carried away and the whole shop is powered off at about 2000hrs.

a) NTFS is running over fuse and is not so efficient b) how is the disk connected? USB is simply slow
normally i would do this on a eSATA with ext4 or if possible on an internal disk and after the source machine is up again you have all time of the world to bring the data on whatever medium
the same for init mysql-replications 1. local rsync while service is up 2. service stop 3. local rsync the get the differences 4. service start 5. now you are up and have a consistent backup
Centos 5.6 I have a 80 gig SATA usb drive connected in hub no-1 and a USB key in hub no-2
If I perform the following commands I get some results but there is no sdbXX appearance

What does dmesg says when you plug it in?
Here it is
ahc_pci:0:8:0: Illegal cable configuration!!. Only two connectors on the adapter may be used at a time!
this looks suspect try googling for it

Look at backuppc. It has a nice web interface to manage it and browse/restore backups and it compresses and pools identical content to hold much more online than you would expect. It is all controlled from the linux side and can work with windows either over smb or you can install cygwin rsync to save bandwidth.
BTW, how may persondays it would require on a Centos 5.7 box to master?
The second time you install it will take about 15 minutes using the EPEL package and having the archive disk mounted under /var/lib/BackupPC (or with a symlink there to the real mount) before the install so everything lands in the right place. The first time will depend on how much you already know about the underlying concepts and tools.
I have squandered away about 75% of available time (of about 2 person days). Amanda, IMHO, requires about 1 person week to deploy initially and about 2 person weeks to get sign-off: am I right about it? or am I inefficient (the "in about 15-minute" is a myth with Centos 5.x maybe truth with Centos 6 -- I dunno)?
It depends on how much you want to know about it, and whether you decide to install cygwin rsync on the windows targets or just use samba against the hidden admin shares (C$, etc.). For the initial setup with the EPEL package the only tricky part is adding the web password for the admin user and possibly others if you want logins restricted to seeing only certain hosts. See the comments in /etc/httpd/conf.d/BackupPC.conf about that.
The docs are at http://backuppc.sourceforge.net/faq/BackupPC.html but you should be able to do all necessary configuration from the web interface after the packaged install, and if you are adding several similar targets, just get the first one right and add the others with 'newhost=oldhost' from the 'edit hosts' link on the web page to copy the configs.
There is a External NTFS partition which will be carried away and the whole shop is powered off at about 2000hrs.
Backuppc uses hardlinks extensively so you'll want that to be ext3, not ntfs, and I'd highly recommend rotating a set of 2 or 3 different disks so you always have a good one offsite. I use a slighly odd raid-mirroring setup myself but it's fairly cumbersome to manage. In any case you need some sort of script to stop the backuppc service and unmount the drive before removing it, and the reverse when replacing, and backuppc has a nightly cleanup process that has to run, so you may have to adjust the timing for it.

I forgot one step there - you also need to edit /etc/BackupPC/config.pl to add the that web login user name to $Conf{CgiAdminUsers}. If you don't log in with a name that matches, you don't see much in the web interface.
And if you want the email warnings about failed backups to work you'll probably need to add a SMART_HOST setting to /etc/mail/sendmail.mc - but that's not really specific to backuppc.

You would want to format the drive with a linux filesystem, though.
Now, that is a typical dilemma that any sysadmin (a lowly and not so respected Job in India), and I can't do that that is a constraint as this external HDD is supposed to be connected for recovery on a (horror of horrors! - winx node in case the centos node fails -- nevermind the neat li'l tar format -- coz everybody in this scenario is afraid of Centos. Well gimme a week. I have at least one Centos box [the elephant in the china shop] to fight with and turn them around :) )
Install VMware player on one or more of the windows boxes. Make a Centos image with backuppc installed and make a few copies of it.
From there it is a couple of mouse-clicks to have Centos running with
a USB device attached to the VM guest. I have this myself on a laptop with one of those generic USB to IDE/SATA cable adapters for whenever I want to access Linux-formatted disks without having to reboot into linux. You might even be able to use the VMware converter tool to turn an already-installed physical machine into a VM image, but I've had more luck doing that with windows machines because I usually install Centos on RAID or with a custom disk layout the converter doesn't understand.
