Re: AMANDA and the Windows world
Hi, Actually in my experience, you are more likely to see development to support other OSes OUTSIDE of M$. What might be an interesting idea is if there is a freeware/opensource backup/restore program for Windows that could be integrated into the AmandaClient... As a long time amanda user I can pretty well remember that this requirement has been discussed quite often in the past... If you have a look at the sourceforge-project Amanda Backup Win32 Clients (which has been abbandonned since 2001), there you can find a small program called nttar, which nicely backs up (and restores) nt acls. I recently tested it - looked quite good. I think it should not be too hard to code a wrapper around this (or to integrate some changes into the source) to make it react like gnutar - and then to integrate it into amanda. Regards, Christopher (who would love to see amanda one day back up windoze boxes natively)
Re: Amanda and the windows world [Q]
Does anyone have experience with an amanda = SERVER in a windows environment ? Unfortunately I don't have any Unix/Linux host available. I compiled the complete amanda package under Cygwin 1.3.10, I just don't know how to start the server and how to connect to the client. I used amanda on different Unices for several years and would like to have it running here, too. Regards Dieter Meinert

I compiled the complete amanda package under Cygwin 1.3.10, I just don't know how to start the server and how to connect to the client. Hmmm... Having just done builds of Amanda under CygWin (client only), I did notice a message from ./configure about some lib calls missing and thus the server would not work.

AMANDA and the Windows world
Hello, I wanted to ask how good is AMANDA to backup Windows servers ? One of the few issues I can think of is: - will it backup a windows file owner permissions and rights (ACL) ? - is it possible for AMANDA to restore directly to a Windows server ? - what needs to be put in place to backup windows servers ? Is there an amanda client for windows ? Thanks for the comments Regards

Is there an amanda client for windows ? There are two ways to back up 'doze clients. See docs/SAMBA in the amanda source tarball and discussions of the cygwin client both in the 2.4.4b1 docs and in the archives of this list. Neither is perfect. Samba definitely won't get ACLs, I *think* it can to direct restores, and it needs nothing more than a defined share on the 'doze client. The cygwin client is pretty new and thus less tested. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University

So, if you're like me, and are really only interested in backing up user data -- not programs, or system files, it'll probably work correctly. I'm still looking around to see if there are cygwin based (or, at least, command line based that can write to STDOUT, as I imagine that's all that's needed) backup programs with do handle acls...

Also, supposing that I use the include list to pass it a set of directories to zip. Could I write a wrapper to replace runtar that would work? I suppose this might create a problem with estimates, and possibly incrementals as well. But Winzip _might_ support that -- I need to look... I'll get back to y'all with what I find... Ricky

As a workaround, you could dump the ACLs with CACLS.EXE to a text file. This would have to be run on each directory you care about, and you'd have to write something to parse the output afterwards and apply it, but it's a start, and doesn't change Cygwin or AMANDA. The output looks something like this: U:\docsCACLS vssver.scc U:\docs\vssver.scc DOMAIN\Domain Admins:F DOMAIN\user:F To make that back into a CACLS command, it would have to look like this: U:\docsCACLS vssver.scc /P DOMAIN\Domain Admins:F DOMAIN\user:F The Perl transformation of one into the other is left as an exercise for the student. But this will do the job.
