Help with amrecover, cannot connect- connection refused
Amanda list: I'm doing my first test of amrecover (amdump ran fine) and I get an error amrecover: cannot connect to tape server name here : connection refused. I tried amrecover as root with all the command line options set except tape device. I have the .amandahosts file set on both the tape server and the client machine, I've checked that the correct entries are in /etc/services and /etc/inetd.conf on both machines and inetd has been restarted. I've read the man pages and the FAQ-o-matic pages, no help. This has got to be a simple newbie config error, can anyone point me in the right direction? Thanks!

Re: Making a copy/image of the backed up data
Simon Frettloeh wrote: If I can read this properly, you suggest to make the copy of the image to the second tape drive. But we need both tape drives for backup reasons. The image should only be dumped to a file. But I think, there would be the possibility to mount a image file as device and tell dd to copy the data to that one :-) Problem could be the variable size of this image device. But thnx a lot for your idea! If you want the images from tape simply dumped to a file, than why don't you use amrestore? amrestore has options to specify what kind of image you want (compressed/uncompressed, with/without amanda header). See man page. Encrypting it and putting it on another tape, can then be done using gpg and dd.

The idea is nice, but it is not as simple as above. Now the while loop tests for successful writing to tape, instead of reading from the source tape until EOT. A real life script would be much more complicated... Just forget that one. Maybe there is some elegant solution using RAIT (never used it; never done it). But I still believe there is more music in a combination of RAIT with a tape and a file driver.

Re: How do I improve performance in Amanda?
But we are using hardware compression. A majority of the filesystem, however, is nfs mounted. Will that slow down the backups?

Re: How do I improve performance in Amanda?
Maybe. If you can, try backing up the filesystems directly instead of via nfs and see if this makes a difference. Ashwin Bijur said: But we are using hardware compression.

RE: maybe this is a dumb question
My policy is to never restore files in place. I always restore to a temporary location and ask the owner to copy the file into place. That avoids any stickiness. I remember a case where someone asked to have a file restored, but it was only to do a diff. The restore was done in place, so afterwards they had the old file, but the new file was gone, which was not an improvement. So this policy protects against stupidity and malice.

Chris, Give your student worker a cookie (or a beer if they're old enough). Though this isn't a new exploit technique, it sure looks to me like if one: - Uses 'program DUMP' - Uses amrecover Then your proposed exploit would work. extract_files_child() in extract_list.c just calls 'restore x', and I just tested that ufsrestore (Solaris) will behave exactly as you describe. If instead you run: amrestore | ufsrestore r you're safe, though this is not so convenient for partial restores. :-) I did not test from inside amrecover; if there is deep magic there I am missing, I'd like to hear about it. From an Amanda point of view, this is an issue with 'program', not with Amanda, of course. I did not test 'tar -xpG' (that's how amrecover calls GNU tar). 2) If it is possbile, are there any security considerations we need to take into consideration when running backups or restore jobs? Yes. :-) I'm *really* glad I don't admin a student or ISP environment! If I did, I would tripwire everything, I guess. - Jay Lessert [EMAIL PROTECTED] Accelerant Networks Inc.

Re: Multiple backups on one tape.
On Wed, Aug 27, 2003 at 01:15:54PM -0500, David Barcelo enlightened us: hello all, I have read the Amanda site and seen the faqo-o-matic about amanda not being able to have multiple backups on one tape. Even though I have read this I am still curious. Is is it still possible to just use one tape during a 1 week dumpcycle and 5 runspercycle policy? Can I get Amanda to append backups? The only way to do this is to let the backups build up on the holding disk and then flush them all at once. This is what I do here since I have 100GB native tapes and not nearly that much data being backed up (yet...). Amanda will not append to tapes, as there is no guarantee the tape is in the right position, and overwriting your backups is not a good thing.

Re: Multiple backups on one tape.
Humm, that is a question. If you had enough spool area AND didn't mind leaving all of your backups on disk (risky but no worse than using a tape drive as the output device) you _could_ fail to mount the tape and run amflush once/week. Couldn't you ? Still, I don't see having a single output tape, you'd have little or no fallback if something happened, spool disk failure, tape failure, drive problems... Dave - not a config I'd recommend. hello all, I have read the Amanda site and seen the faqo-o-matic about amanda not being able to have multiple backups on one tape.

Re: Multiple backups on one tape.
Thanks for the reply. We are using very expensive tapes and the thing I had in mind was recycling my tapes every 4 weeks. Thus I would need 2 tapes per week. 1 for incrementals (Mon-Thurs) and 1 for full backups (Fri). A grand total of 8 tapes plus one for good measure. We are spending about 40 ducets a tape. Very pricey. I agree that it isn't the most sound configuration but if I can make it work I am willing to try. If I use amflush will I still be able to index incrementaly backuped files on the tape. In other words, off the top of your head (or anyone elses) what amanda utilities will become unusable and/or ineffective do to this unusual configuration?

Re: Multiple backups on one tape.
Dave, I was afraid you where saying one tape total. Yes, your config should work. Did you figure out how you'll schedule the fulls for friday ? amadmin force from cron ? Dumps will remain distinguishable from one another, the files on tape are node_disk_date.level athena_usr1_20030812.2 - Level 2 dump on 12 August this year for Athena:/usr2 or something really really close to that format. Humm, maybe its dots and not underscores, slashes are replaced by underscore I think so root partition may be athena._.20030812.2 Thanks for the reply.
