A few ideas, which might be useful for the future at least: 1) switch to GNUTAR (I was using GNUTAR but had ended up switching to ufsdump due to some problems); 2) there used to be a binary compatibility layer that let you execute Solaris executables on Linux, but maybe that has disappeared, or at least would probably require compiling a custom kernel; 3) look for source code for ufsrestore, but I don't think it's Open Source; 4) Can Solaris run under VMware on x86 architecture? 5) look for Open Source libraries that can parse ufsdump format, or ufs filesystem, and write your own code.

Such a traditional way of backing up is exactly what amanda tries to get away from. Amanda mixes some full backups and some incrementals each day with the aim of a consistant sized backup each day. No more 18 hour, 300 GB dumps on Sunday and 2 hour 10 GB dumps other days. Instead amanda does 60 GB dumps daily, including Sunday. (I forgot to explain that I have 2 DLT tapes backuping the datas).

I figure this setup will give me a full backup every Monday. Is that right? If backups are only run Mon-Fri (5 days), and your dumpcycle is 7 days (1 week), then your runspercycle should be 5, not 10. Runspercycle is how many runs per dumpcycle, not tapecycle. Now how do I configure amanda to do differential backups (level 1) on Tuesday thru Friday? One email I found in the archives suggested setting bumpdays to 4 but wouldn't that mean level 0 for four days? You're trying to force amanda into your schedule (full Monday, incremental otherwise). The way amanda expects to be run is to be given the parameters above, and then be left alone to set her own schedule of full and incrementals within those parameters. IOW, she'll try to balance out the backups so that each night's are about the same size as the previoius nights while making sure she does (in your case) level 0 of each FS at least once a week. I haven't played around with bump settings, so I can't help there. I can just say that, unless there's a *really* compelling reason, it's best to let amanda set her own schedule. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University

Runspercycle is how - many runs per dumpcycle, not tapecycle. OK, I think I've got it :-) What is important is that if any tape -- say Wednesday's tape -- is destroyed (earthquake, fire, airplane) I can still restore the databases files up thru Tuesday from whatever tapes are in the archive. The DBA tells me he can restore the entire database from the files on the volume I am backing up as long as I can restore these files. Because of how the tapes are rotated, that means all I can be sure to have is Monday's and Tuesday's tapes plus all the tapes from last week. If the amanda scheduler makes this possible, then I am happy. - Now how do I configure amanda to do differential backups (level 1) on - Tuesday thru Friday? One email I found in the archives suggested - setting bumpdays to 4 but wouldn't that mean level 0 for four days? - - You're trying to force amanda into your schedule (full Monday, - incremental otherwise). The way amanda expects to be run is to be given - the parameters above, and then be left alone to set her own schedule of - full and incrementals within those parameters. IOW, she'll try to balance - out the backups so that each night's are about the same size as the - previoius nights while making sure she does (in your case) level 0 of each - FS at least once a week. Like I said above, it doesn't matter as long as I can be certain that I can restore the database and systems files. -- -- Stephen Carville http://www.heronforge.net/~stephen/gnupgkey.txt == Government is like burning witches: After years of burning young women failed to solve any of society's problems, the solution was to burn more young women. ==

I have done the entries for services and xinetd.conf and restart xinetd. Now when I run amcheck I get the following error. You should really test as the user you intend on running amanda as, otherwise the testing really isn't valid. What user did you tell ./configure when you compiled amanda? ERROR: localhost: [access as amanda not allowed from root@localhost] amandahostauth failed You need a file called .amandahosts in the $HOME of the amanda user (determined at configure time). In that file you need an entry for localhost and for 'localhost root' (the second only for amrecover). Again, the amanda user. The reason I am using root as a testing is because I cannot get to do the test as amanda su amanda amcheck DailySet comes up with error The way to do that is: su amanda -c amcheck DailySet And please turn off Outlook's send as HTML feature -- email is a text medium and HTML just wastes bandwidth. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University

What I cannot seem to figure out is supposing I have 8 machines ( 1 main server 7 others) want to do a full backup of the main server every night a full backup of one other machine per day either in rotation or ad-hoc how can I persuade amanda to allow me to label / rotate tapes manually always do a full backup of the specified machine? Look into amadmin config force. You could script this so that full dumps are scheduled for when you want. However, I recommend against this. Amanda's scheduler does an excellent job of deciding when to do a full dump of each file system in the interest of keeping the time for the amdump run roughly the same. Forcing full dumps will just screw up the schedule and Amanda will do a better job than what you are planning. $.02 It appears to me that much effort has gone into the scheduling etc but I am completely unclear as to how I might just say "backup machine 10.0.78.56 ( or whatever ) in full to whatever tape happens to be in the drive - no arguments - no wrong tape etc just do it!" . - Or for that matter restore a file / group of files from tape in drive to machine xx.xx.xx.xx:/directory/subdirectory You seek amrecover, some time spent with the documentation would be well spent.

Re: your mail
Joi et al: (I'm not positive about the read-write, but it definately needs read.) It appears that AMANDA must write to: * its config directories * /etc/dumpdates (if you're using dump) * /etc/amandates * /usr/adm/amanda or wherever you've set the log directories to * /tmp If it can't write to any of them it can simply die silently. No error. Nothing - especially if /tmp fails. amrecover and the index server seem to be the most susceptible to non-writable directories, although amandad and almost anything else that logs to /tmp can fail silently. I'm inclined to hack the source and stop it from dying without a trace; maybe a syslog of messages.critical saying there is no AMANDA logs would be better than being stuck without a backup! I must confess - although I've found AMANDA an excellent backup system and I've restored from it a number of times - I find that its error reporting is absolutely woeful and/or non-existent.
