Libraries and multiple drives setup in amanda.conf
I have changerdev setup and working but I have 2 DLT8000 drives. What I am wondering is how do I tell amanda about 2 drives? Right now I have this in the amanda.conf: tapedev /dev/st/nh0c0t1l0 # the no-rewind tape device to be used But that is only one of the two. Should this be something different? My 2 drives are: /dev/st/nh0c0t1l0 /dev/st/nh0c0t2l0 I think I may be getting close to a working config. Thanks all. Mark
Re: tar/ not missing any new directories

Yes, that's what I'm doing. The problem with this is that something
easily gets left out as new directories are created.
I'm late to this conversation, but I don't think it is possible to
leave out any new directories with a scheme like this:
define dumptype diskA-TheRest {
comp-user-tar #or other local globally defined TAR dumptype
exclude list /diskA/diskA.exclude
}
on client,/diskA/diskA.exclude contains:
fred
sally
sam
tom
on server, disklist:
client.fqdn /diskA diskA-TheRest #excludes fred,sally,sam,tom
client.fqdn /diskA/fred comp-user-tar
client.fqdn /diskA/sally comp-user-tar
client.fqdn /diskA/sam comp-user-tar
client.fqdn /diskA/tom comp-user-tar
(a) when remembered, add a new directory by editting disklist
(explicitly add deb and client:/diskA/diskA.exclude explicitly
exclude deb
(b) when forgotten, new directory is already included in the
diskA-TheRest because you haven't explicitly excluded it.
Yes. I think you are right.
The fact that two separate files have to be maintained is a drawback,
though, but I understand that with Amanda 2.4.3, that won't be necessary
as multiple exclusions can be listed in the dumptype (which could be
inlined in the disklist file.)
I still think a way to automate the split process would be useful,
though...

Error with barcode reader Email Message
Hi. I'm having a little trouble understanding why everytime I run amcheck or amdump I receive a large email with the subject Error with barcode reader on Fri ... and contains a list full of enties like:- Fri Nov 8 10:38:05 GMT 2002 Invoked with args '-info' STATUS - currently loaded slot = -1 INFO - current slot -1, last slot 9, can go backwards 1 Fri Nov 8 10:38:05 GMT 2002 Invoked with args '-search BacypMis12' SEARCH - WARNING!!! BacypMis12 not found in current ADIC- barcodes database. - WARNING!!! Check your typing, and/or update the database. From my point of view, the barcode reader is working perfectly. I can still run inventory commands etc. Even when amcheck is running the autoloader still looks for and locates the correct tapes but when either amcheck or amdump begin, amanda sends out the message! Any ideas would be most welcome Thank you!
Windows backups
Hi All Quick one, can amanda backup open files on windows using samba, and if not how can i backup open files on amanda ?? Thanks
RE: Windows backups
Hi , We had that issue - we couldn't backup our exchange files while exchange was up - so we put in scheduled job to switch off Exchange while the backup was in progress - and then another one to start it up again once the backup was completed. Works a treat. If you want the .bat files let me know and I will publish them in the list.

Re: Windows backups
Du-Wayne Rood wrote: Quick one, can amanda backup open files on windows using samba, and if No. not how can i backup open files on amanda ?? I do it the other way around. I create shares on a unix/linux server and run samba on the server. Everybody uses these shares to store their data. (Yes, this gives problems with e.g. Outlook users etc, who have to modify the defaults to store the mail on the share etc. and laptop users who _need_ data on their local drive, but laptops are not around at night when amanda runs anyway.) Then I make the backups with amanda from the unix-host: no problems with open files, and much faster too. Some shares do reside on Windows-servers, but I try to keep most of them without write access; this avoids the open shares problems. Does there exist a native Windows program that can backup open files? The standard backup program on e.g. win2000 can't (but most pc users are not aware of that problem :-). ps.

- support public key encryption type of schemes 'pgp' or 'openssl' style

You should read the SECURITY-API file in the docs directory, that's the
design to handle that; the API is in the 2.5 code (that is, the main CVS
branch) If you want to roll up an openssl and/or pgp security module to
go with the current bsd, krb4, and krb5 ones, and would like to
contribute it, go for it!
- support signing the data (instead of a crc or sha1 or rmd160), one
can use pgp, gpg, or openssl for this
Not sure if one could call that a compression scheme or what... That
would be the usual kluge in the current versions of Amanda, configure it
to use /usr/local/bin/compress_and_sign instead of /usr/bin/gzip, and make
compress_and_sign a program that compresses and signs the archives. Then
archives that you compress on the client side would be signed, and the
uncompress operation would check the signatures.
- Would there be a way for individual users to restore their own files without
compromising system security (aka currently, anyone who is allowed access to
amanda via 'amrecover' can restore any file).
I've thought about this somewhat; it would require some serious infrastructure
changes; basically
* the indexing would have to include better file permissions/ownership
information so amrecover could tell who owns the files on the tape
* amrecover (and any code it calls) would have to be thorougly reviewed for
setuid safety.
* You would have to have it amrestore the files into a /tmp directory
that the user can't get at, then change the modes so the user can
read it when you're done; otherwise you would have to fix amrecover,
tar, and all the {ufs,vfs,...}restore utilities to be symlink-race-proof;
and that's not likely to happen any time soon.
Then you could make amrecover setuid and off you'd go.
aka the above suggestions of encryption/signing are for storage in the
holding disk (since I have configured mine to be _the_ place data is stored,
tape drive not hooked up yet), or to tape. To do this of course the amanda
user would have to have access to the keys.
You would probalby want to give your amanda user its own PGP key, and have
everyone sign the data and encrypt it to the amanda user...
Why can't amanda backup open samba files?
Would somebody explain why amanda can't backup Windows files over SAMBA that are open? I'm confused by this because I know that multiple people can open a file on a Windows share over a network (or at least I thought they could). If multiple people can open a file on a Windows share, why can't amanda open and read that same file even though it's open? -- Carl D.

There are Windows calls to break open file locks; BackupExec, Legato, and other commercial packages can use software that does it, and the files get backed up (for suitable values of backed up), but it: a) sometimes confuses the software that has the file open, and b) backs up contents of the file that aren't neccesarily in any sane state since the application (i.e. email server, database server) has stuff cached that isn't on disk yet. So even though there's stuff that *can* do it; I'm not sure you *want* to. It's much better to make an application dump (i.e. database table dump) and back that up, or stop the application for the backup. The samba server solution fixes a) but not b). marc
Requesting comments on a possible amanda configuration
I'm trying to setup an AMANDA backup system with the following characteristics: Full backup every Wednesday on a different weekly tape Differential backup on Thurday, Friday, Monday, and Tuesday Full backup on the last Wednesday of each month which is then archived for a year. So far I've setup a Weekly configuration with runspercycle set to 0, dumpcycle set to 0, and tapecycle set to 7. record is set to yes so that differentials run on a daily basis will have a date that the last full backup was done on. I have a Monthly configuration with runspercycle set to 0, dumpcycle set to 0, and tapecycle set to 14. Again, record is set to yes for the sake of the daily differentials. The Daily configuration is runspercycle set to 4, dumpcycle set to 1 weeks, and tapecycle set to 7. I have cron setup to run amdump Daily on Monday, Tuesday, Thursday, and Friday; amdump Weekly on Wednesday for the first 3 (or 4) weeks of the month; and amdump Monthly on the last Wednesday of the month. Does this sound like my configuration will do what I want? Or do I have something really messed up? Any comments or suggestions would be appreciated. -- Carl D.

Re: Windows backups
Dear Paul Bijnens, Once you wrote about Re: Windows backups: Does there exist a native Windows program that can backup open files? The standard backup program on e.g. win2000 can't (but most pc users are not aware of that problem :-). Google for open file manager. OFM is used by several backup products (e.g. Novanet from NovaStor). OFM simply keeps track of all open file on the system, and, when asked by backup or any other software, provides the lates copy it has. We've used it for the last couple of years and it works stable and does the job. It can be purchased and installed separately on each server without any backup system. -- Best regards, Leonid Mamtchenkov, RHCE System Administrator Francoudi Stephanou Ltd.

But if someone opens the file for writing, you will, most probably, run into all sorts of different problems, starting with Permission denied errors and ending at corrupted contents. Good luck. :) -- Best regards, Leonid Mamtchenkov, RHCE System Administrator Francoudi Stephanou Ltd.
