Copying data to new tapes
Hi, we used a Tandberg Superloader DLT Autoloader for offsite backups. Now I ordered a Tandberg Storageloader LTO3. Does anybody of you see a way to get the data of the old DTL to the new LTO3 tapes? Doing a 1-to-1 copy is wasting many space and money. My only idea is restore everything on the old tapes to a huge place and backup it to LTO agin, isn't it? But this would be to much work.

When copying Amanda tapes to a larger media, I read all parts with dd as long as the capacity of the new tape is reached and then I write these parts to the new tape with dd. In order to recover you should position the tape manually (with mt), and you must disable amrecover_check_label in amanda.conf (otherwise amrecovr would rewind and see the wrong tape label at the beginning of the tape.

I create a listing, print it on paper and store it together with the
tape.

Re: Copying data to new tapes
amanda can't do it automaticaly, but it is planned. You could restore everything on the holding disk and use amflush to flush them to the new tape. amrecover will correctly works with the new tape. if your blocksize on tape is 32k, it is a simple as: cd /holding/disk/path. mkdir 20070101010101 cd 20070101010101 for all old tapes amrestore -r /device/name rm all dump that are complete. amflush You should verify the result.

Re: Barcode labels for LTO, DLT, ...
Dustin J. Mitchell [EMAIL PROTECTED] writes: On Nov 11, 2007 1:24 PM, Sven Rudolph [EMAIL PROTECTED] wrote: following the ideas from the discussion some months ago I implemented just another tool for creating barcode labels for tapes. It is written in Perl and uses the Barcode Writer in Pure PostScript. Currently it creates labels for DLT and LTO (Ultrium). I'd like it to become even more generic, but the way of specifying the label layout is still a bit inflexible. So I first want to show you what I did, and you can tell me what is needed... Neat! As I understand it, this is a generic label-printing utility, which could be used with any backup software. The code looks quite well-designed and extensible -- quite a feat for this sort of task. Are you interested in further integrating it into Amanda? Currently the only Amanda-specific thing is that you can print a descriptive label name in addition to the barcode text. In the default configuration most barcode libraries use only 8 characters, and with the tape type specifier (like L4, S4) you have only 6 characters. So I wanted to print the label names used by Amanda (like Set1-Jan-01) on the label. The label-printing that Amanda supports is a bit inflexible -- it's treated as a kind of report and (as you probably know) makes some assumptions about the format of the postscript template. I think the barcode labels have another purpose: They identify the media. Before I amlabel a tape, it gets its barcode label. (And amlabel (together with the changer script) reads this and stores it in an internal database. On the other hand the amreport labels are used to list the content of a tape. I use them for the off-site tapes in order to make a bare metal restore (without the index files) easier. So I use both, the barcode labels and the amreport-generated labels. I'd be glad to see this used together with amanda, and it could be good to distribute it together with amanda. But currently I don't see a way to integrate it more closely.

Gentoo has some unusual defaults for Amanda's various configure options, although I don't see anything about sysconfdir, or defaulting to /usr/local. Did you build from the ebuild?

So as you can see it's a mess and I'm not sure about the configuration :)
