support for removable (RDX) disks
Hello, tried with forums, but got no reply, so I'm trying here now... I'm considering to upgrade my current backup system consisting of Amanda and LTO-2 drive/tapes. My needs are to regularly backlup my desktop machine (2X1TB disks in raid-1) and occasionally perform backup of my netbook (320GB disk drive). Besides that I have collection of 13 LTO-2 tapes mostly uncompressed material (old hi8 movies and scanned negatives). Considering that LTO tapes are quite expensive and I'd have to buy at least LTO-4 if not wanting to skip over two-generations lap, I'm considering to switch to RDX disks/cartridges and wonder if anyone can share their experience of using Amanda with RDX disk-based backup? By looking at docs, I've found the following: How To:Using removable hard disk changers as Virtual tapes from the wiki (forum software does not allow me using URLs ), but would like to hear if/how Amanda is suitable for the task? Sincerely, Gour
slow estimate on FreeBSD/ZFS
Hello, I was able to somehow re-do my Linux backup and restore data on Free/PC-BSD-10.0 and thanks to Heiko's encouragement I've stayed with Amanda as my backup solution. :-) Now, I've problem that estimation for my OS -- 600GB alltogether, split in 11 DLEs entries takes enormous long time in comparison with the time it took on Linux/ext4. Here is my df -h output: [gour@atmarama] /var/db/amanda# df -h FilesystemSizeUsed Avail Capacity Mounted on tank/ROOT/default 356G6.6G349G 2%/ devfs 1.0K1.0K 0B 100%/dev procfs4.0K4.0K 0B 100%/proc linprocfs 4.0K4.0K 0B 100%/compat/linux/proc tank/tmp 349G1.3M349G 0%/tmp tank/usr/home 356G6.9G349G 2%/usr/home tank/usr/home/gour896G547G349G 61%/usr/home/gour tank/usr/jails349G 32K349G 0%/usr/jails tank/usr/obj 349G 31K349G 0%/usr/obj tank/usr/pbi 351G2.1G349G 1%/usr/pbi tank/usr/pbi/.pbi-world-amd64 350G537M349G 0%/usr/pbi/.pbi-world-amd64 tank/usr/ports349G270M349G 0%/usr/ports tank/usr/ports/distfiles 349G 36M349G 0%/usr/ports/distfiles tank/usr/src 350G1.2G349G 0%/usr/src tank/var/audit349G 33K349G 0%/var/audit tank/var/log 349G493K349G 0%/var/log tank/var/tmp 349G 32K349G 0%/var/tmp tank/usr/jails/.warden-template-10.0-RELEASE-amd64349G178M349G 0%/usr/jails/.warden-template-10.0-RELEASE-amd64 So, few questions: a) what is the reason that estimate on FreeBS/ZFS is so slow in comparison with the Linux/ext4 (I had raid1/lvm2 setup)? b) as a workaround I put: estimate calcsize in my dumptype and wonder if there is some serious trade-off in it? c) amanda-hackers mailing list is subscribed to gmane similar to this list, but the former allows direct posting via gmane, while this one does not not? Can someone do something to allow posting via Gmane for amanda-users or do you allow that I contact Gmane maintainers and try to edit the current setting?

You can set it to 1. So, besides moving (again) to Free/PC-BSD, I want to move back from Bacula to Amanda... The main reason for using Bacula (again) was problem building Amanda on my machine: In file included from /usr/include/glib-2.0/glib.h:72:0, from amanda.h:39, from amxml.c:33: /usr/include/glib-2.0/glib/gqueue.h:76:10: note: previous declaration of 'g_queue_free_full' was here but I'm sure Amanda is better supported on Free/PC-BSD than on Archlinux. Another reason for re-considering Bacula was (possibly) quicker restore times due to deploying PostgreSQL database and having index available. (I'm familiar with cli and lack of GUI is not the reason, I use bconsole.) However, setup of Bacula is more complicated, requires more admin work (which I'd like to avoid) and not much gain for it (only quicker restore). So, my multimedia stuff (archived videos and scanned 35mm slides) are stored on 'amanda' tapes, but now I'd like to deploy it for my regular desktop backup. Am I correct if I consider using 'one DLE per single tape' strategy is better than spanning backup on several tapes? My backup device is single LTO-2 drives and the current Archlinux OS takes ~12G for / (linux OS) and ~560G for /home. I know that with FreeBSD it will be different (we'll use ZFS with some more slices for OS), but the main portion of backup is /home. Now, I wonder if you can give me some advice how to divide my /home (there is only one account under /home/gour) into DLEs to fit on a single tape or it is better to use tape spanning? I mean, how one is one supposed to handle backup when DLE is greater than tape capacity in general? Of course, I can divide /home/gour into several DLEs/tape based on *current* disk usage, but it may change in the future? How to handle it?

Hello, during my migration from Linux to FreeBSD I lost Amanda's logs and cannot use amrecover. In the attempt to re-do backup I wanted to amrestore content from the tapes, but one set of tapes was dumped with software compression enabled and now amrestore reports: amrestore on fbsd on compressed .gz tape (on linux) failed with: ERROR: /usr/bin/gzip exited with status 1. Any hint how to overcome it? (It's multi-tapes backup and I need to amrestore first and then to concatenate all the parts.)

I'd wager you wouldn't be able to differentiate using an LTO-2

Hmm...
Unless things have changed, amanda uses the filemark in calculations
like:
[...]
In my limited experience with various tape formats and tapetype,
I found my LTO-1 drive to give virtually identical results each
run across different individual tapes and 2 brands of tape. The
filemark was always 0. In contrast, my tapetype results for DAT
(DAT-2 and DAT-3) were a bit inconsistant and showed definite
differences between brands.
Interesting.
If my amtapetype results showed a significant filemark while
others generally report zero filemark for LTO formats, I'd ponder,
but wouldn't worry too much, why I got my results.
Well, that's why I'm asking...all the entries for LTO-2 drive in wiki
have filemark 0k.
I'd certainly rerun amtapetype. It not that big a hassle. You
could have done that before asking and had your result before any
replies to your query.
That's what I'm doing now, but it takes some time...
I'd also look at the reported throughput. Amanda makes no use of
the speed results; those are for your info only.
OK.
I'd compare my observed results with other reports and with the
drive manu- facturer's specified speed. If your system is unable to
feed your drive data at a rate sufficient to keep it streaming, I'm
pretty sure that apparent capacity and filemark can be affected.
The speed which I got (22522 kps) is in the boundary of other's
results) in the wiki as well ac close to HP's spec of 24Mps.
Now I'm doing test with compression disabled.
Here is the result:

Bacula -- Amanda migration
Hello! I've 8 LTO-2 tapes filled with raw video (DV) and 4 with raw high-resolution (35mm) scans stored in Bacula catalog in Postgres database. Now, I'd like to put this data (~1.7TB of video 700GBs of scans) on the tape backed up by Amanda. I'd also like to do this migration while my desktop machine is still running Linux (with ext4 fs) 'cause I plan to put Free(PC)BSD on my desktop with ZFS filesystem soon, in the attempt to avoid migrating Postgres database from one OS to the other. As far as I can see, there is no way to avoid restoring all this data and then do backup with Amanda. The problem is that I'm a bit tight on the HD - my desktop has 2x1TBs hard disks running in raid1 mirror, and two smaller external USB disks (320GB + 750GB), so the only solution (without buying more hardware) seems to be to remove one disk from raid1 array and used it along with the other disks to restore everything on those and then backup? Let me add that video files (8 tapes) are stored in separate catalog then the slides, iow. they use different pools of tapes. Any idea how to do this Bacula -- Amanda migration in a most simple way? Is there any concern when migrating Amanda from Linux to FreeBSD? Can you recommend some appropriate strategy to do this long-term archiving of video slides (besides http://wiki.zmanda.com/index.php/FAQ:How_can_I_configure_Amanda_for_long-term_archiving%3F) in order to have it easy way when doing recovery/restore without having all the eggs in one basket?

The short answer was that there is no way except recovering and then backing up with the new backup program. :-( If you had two tape drives and a decent sized holding disk, and you wanted to get really creative, you could write a module that recovers from Bacula tapes and streams directly to the Amanda backup. ;-) But, that's *way* over the top. Much easier to just recover and back up again. Neither I've two tape drives, not enough creativity to delve into such project. :-) I've found that using amadmin to force full and then marking the tapes as no-reuse works for archive and ends up keeping the same configuration for DLEs, etc. Good. If you want more than one copy, you can always run that again, or just copy the tape if you have two drives. Bacula has Copy Job. What about Amanda's amvault? Can it serve the same purpose?

Amanda vs Bacula
Hello, I'm an Archlinux user planning to migrate to Free/PCBSD soon. At the moment I use Bacula to backup my desktop machine and another (old) laptop. Moreover, I've collection of archived (scanned) slides and video files which are archived on (atm) 12 LTO-2 tapes with more tapes to be filled in the future. So, considering the above backup hardware (HP Ultrium 448 tape drive) and my backup needs, I wonder whether Amanda might be better option for me? When I say 'better' I think about the following: a) ease of setup and admin work required to maintain the setup I did configure Bacula, created 3 different Catalogs (video, slides, desktop). but I lost in the past my configuration and had to scan all the tapes to restore catalog files which are atm stored in Postgresql database which is another extra requirement to admin. (Let me say that I keep Postgresql just for the Bacula needs. How does Amanda compare here? b) tools for working with the application Bacula has Bat GUI, but I use bconsole and can find my way there, but wonder how does Amanda compare here? c) bare-metal recovery So far, I never did it with Bacula, but I confess that I'm not probably ready either. Is bare-metal recovery easy/difficult with Amanda? d) spanning volumes on more than one tape and appending to the tape I see two unusual (from the Bacula user's perspective) FAQ entries: 1) How do I back up a partition that won't fit on a tape? 2) Why does Amanda not append to a tape? According to the FAQ, answer for 1) seems to be that it's possible since 2.5.0, and it looks that 3.2.x is bringing support to even better level. Correct? As far as issue 2) is concerned, I'm accustomed in Bacula to simply run a job, selecting correct Pool of tapes and Bacula appends new backup to the appropriate tape without much thinking. It looks that Amanda is using different strategy, and the following confuses me (from http://wiki.zmanda.com/index.php/FAQ:Why_does_Amanda_not_append_to_a_tape%3F): ...Amanda was designed to never overwrite a non-Amanda tape, nor an Amanda tape from a different configuration, nor an Amanda tape from the current configuration that is still active, i.e. has backups on the tape more recent than the dumpcycle length. Bacula also has 'file retention' parameter, but here I'm confused with interchange of the words 'append' (as used in the FAQ entry) and 'overwrite' as used in explanation? So I'd appreciate if someone can throw some more light on it helping with the final decision. Anything else which I did not include which might be worth of comparing?

It is my experience that once you get the configuration files set up, everything is very stable. That's good. Amanda does not address bare metal recovery. I, however, do. http://www.charlescurley.com/Linux-Complete-Backup-and-Recovery-HOWTO.html. Nice article. The quantum unit of backup in Amanda is the Disk List entry (DLE). A DLE may cover more than one partition or a portion of a partition. You can use exclusions to further refine and nest DLEs. That's clear. One thing that concerns me with appending is that if the tape or the tape drive goes bad during the append operation, you run the risk of clobbering no only the appended material but also the previous material. Having seen this happen, I prefer to avoid it. Tape space is much cheaper than your data. I see... Also, with virtual tapes (vtapes in Amandaese), the question is meaningless. It is the total space available in the partition that is critical, not the available space on each vtape. So, I can create as many vtapes as I like and then dump those to the tape and they can span many tapes if required? One of these days your tape drive is going to wear out. You may find it expedient to replace it with disk drives loaded with vtapes. Well, my 'multimedia' archive is meant to be archived and here I assume tapes, not on the movable hard disks. For me, the lack of vtapes in Bacula would be a show stopper. Thank you for your input...I'm going to take a closer look at vtapes in wiki.

For, example, I'm totally happy with a simple command line interface, whereas some people won't even consider a piece of software unless it has some sort of graphical interface, even if it is just a web interface. I like cli and do not have problem with it. ;) Anyway, that's just by way of illustration. When you mentioned Java, I had enough. :-) If you want a general sense of why I like Amanda, see http://blogs.umass.edu/choogend/2007/09/27/ten-things-i-like-about-amanda/ . It's slightly dated, but still pertinent, in spite of both Amanda and Bacula having seen a huge amount of development work in the last few years. Very nice article. I really enjoyed it. ;) That was a significant part of my choosing Amanda. It is pretty much straight to the point. You don't have to install and configure an SQL database (and manage it's tuning and performance); you don't have to configure multiple server daemons (storage, database, backup); it is run from the OS (cron), so you don't have to worry about whether it is still running or not (having to put in a nagios module to watch it); it uses native tools on the OS, so you don't have to worry about being able to read the tapes if your backup server goes belly up; and I believe the configuration of Amanda is much easier, as long as you get the point of the planning strategy that Amanda uses -- Huh...this is very true and compelling... If you go with the enterprise edition from Zmanda, you can get a graphical console that is very advanced. I'll stay with community version, but don't have need for gui. Bare metal is bare metal. I don't think there is much difference in concept getting your system back up. The huge difference is that Amanda tapes can be read with native OS tools. So, you don't have to get Amanda installed and reconfigured in order to access your tapes. This is huge advantage. append is the idea that one backup run can be added to the end of a tape used by the previous backup run, continuing until the tape is full. Some (including me) are philosophically against that. It poses risks of losing all those backups if one fails in writing to the tape, and it eliminates the redundancy of your backups by putting all (or many of) your eggs in one basket. I prefer more tapes and don't mind if they happen to be largely empty. That just means I still have growth for the future, which is always an issue. Heh...more eggs in the basket is good explanation. overwrite is when a tape comes around for being re-used. Well, I understand about 'append' 'overwrite', but wonder why the FAQ entry is named Why does Amanda not *append* to a tape? while the answer speaks about: ...Amanda was designed to never *overwrite* a non-Amanda tape.. It looks that FAQ entry mixes the concepts? So, the re-use of tapes by Amanda is somewhat simpler. Right. No need to extra layer of Pools as in Bacula...We like simiplicity. It is controlled by the tape cycle. If you want to use a tape as an archive (set aside and not re-used), you can use amadmin to mark that tape as no-reuse. This is nice simple. We might use it for our 'multimedia archive'. ;) I hope that helps. Yeah...I'm thankful to all those who responded and I believe I'm going to install Amanda. :-) Question: considering that I may start using Amanda while still being on x86_64 Linux, what would be procedure to migrate my setup on x86_64 Free(PC)BSD?

You set a configuration value to the maximum number of tapes to span. E.g.: I allow two. Most of the time Amanda uses one. OK. That's nice to hear. However I have a few large DLEs.

If you use more exotic filesystems (reiserfs, xfs) you may need to use yet another dump command. On Linux I use ext4, but plan to use zfs on FreeBSD.

My concern is that physical tapes die, often unexpectedly, and at that time your choice is either to buy a new tape drive or toss your tapes. Well, hard disks die too. :-) The latter is attractive if you already have a known good alternative up and running. In order to have some redundancy, Bacula has 'Copy Job' option to duplicate volume. Probably it can be (somehow) achieved in Amanda setup?
