Amanda has stop daily e-mail reports.
Hi All, Has anybody come across this before. Amanda appears to be working fine, but has stop mailing reports out after backups or flushes. I have tested mailing service on the server and they appear fine. Also what is the script that runs the mailed report? best regards R L EDWARDS

Hello, Few month ago, I was told to apply this patch : http://cvs.sourceforge.net/cgi-bin/cvsweb.cgi/amanda/server-src/taper.c.diff?cvsroot=amandaonly_with_tag=amanda-242-branchr1=texttr1=1.47.2.15r2=texttr2=1.47.2.16r2=textf=u but now the page doesn't exist anymore, and when I follow the link to the new page I don't know which patch to choose. Anyone can help ? Thanks in advance regards -- Olivier Collet System Administrator If you ask questions, you might look stupide, but if you don't, you will be stupide.

One-time Full backup
I often have systems about to go through scheduled hardware maintenance, and I want to run a one-time level 0 backup of it prior to the maintenance and outside of its normal schedule. Once the maintenance is successful, this particular backup isn't needed any longer. I've created a configuration for it, and I'm just wondering if amanda will work correctly with: dumpcycle 1 runspercycle 1 tapecycle 1 and allow me to re-use the tape for the same thing next time.

What you want is a bootable CD which contains the tools to format a disk and tar/restore from the amanda dump. linuxcare provides an image for a bootable CD http://open-projects.linuxcare.com/BBC/ Or maybe you can use the CD you installed linux from. Since the crashed machine almost never has a tape driver, you'll end up doing something like rsh amandahost amrestore -p host filesystem | tar xf - I use dump/restore (yes, I hear the groans) and have had problems rsh'ing to restore, so I usually amrestore the archive to a file and then extract from that via nfs mount or copying the file to the machine. Amanda documentation describes the command. And you'll need to fiddle with lilo to the make the drive bootable. You should find a guinea pig machine and try this! One surprise I had with the linuxcare CD was that it created a filesystem which was a slightly newer version of ext2. The restore went fine, but afterward dump failed, complaining that the filesystem was a newer version than the dump version. Replacing dump with a newer version fixed that.

Easy Questions
Hello, I have a question about dumpcycle/tapecycle and reusing tapes. Firstly I have dumpcycle = 7, and tapecycle = 40. I used 40 because I wanted a months worth of tapes before I reuse a tape, + 10 for extra tapes. Is this logic ok? Tomorrow I want to reuse tape 1. Can I just put tape 1 in the drive, or must I run an amrmtape before I can reuse it. Thankyou for your time. Andrew Hall

Response to r.f.c.: Suggestions
hi. Since the Amanda 2.4.2 INSTALL file requests PLEASE send mail to [EMAIL PROTECTED] if you have any comments, i made a few suggestions/notes during my install. First, though, in the INSTALL or README, say that understanding all one should of Amanda is not trivial, and that Amanda is not appropriate for every situation where computers outnumber tape drives. For my 2-computer setup, for example, using just NFS and tar is far, far simpler. Replace 2.1.B.'s example config directory, /usr/local/etc/amanda/confname, with one that exists by default (/usr/local/etc/amanda didn't exist). It's hard for the 1st time installer to figure out the best place for these things. Where appropriate in INSTALL, inform the installer to make use of disklist, amlabel, and amcheck (not just re:crontab), and to see each's (and Amanda's) man page for how. Consider moving section 2.1.C to the end. Most people will want amanda working before adding it to their crontab. In section 2.2.A, mention that .amandahosts uses the same format as .rhosts, and give an example line. Use a different name for either the FAQ file or the db at http://amanda.sourceforge.net/fom-serve/cache/1.html because calling them both FAQ is confusing. Though she's more than i can handle at the present, for the future, thank u for keeping amanda free and well-supported. george herson

Re: Amanda has stop daily e-mail reports.
Has anybody come across this before. Amanda appears to be working fine, but has stop mailing reports out after backups or flushes. I have tested mailing service on the server and they appear fine. Also what is the script that runs the mailed report? It's amreport that generates the E-mail. In fact, you can re-generate a report like this: su amanda -c amreport config -l log.MMDD.NN It runs the mail program like this: mailer -s the subject mailto the-letter where mailer is the mail program (amadmin xx version | grep MAILER) and mailto is the mailto value from your amanda.conf file (amgetconf config mailto). So try putting a few lines of text in a file and running the above command sequence with the appropriate substitutions as the Amanda user and see what happens. R L EDWARDS John R.
