tape backup vs hdd backup
Hi, I am new to this list. I work in a company as admin where AMANDA is implemented as a BackUp System, so this list is exactly what I was looking for. Also I am new to Amanda. I've never configured amanda from scratch. Here in the firm, the former admin has configured amanda and now I have it working. Last days a colleague asked me why are we using tape backup which is more complicated and why do we not use an external 250 GB USB/Firewire HDD. I didn't know exactly what to say. I know all companies have tape backup, but which are the real reasons for that. Why not to use an external 300 GB USB HDD? What do you think? All the best, ddaas
Re: tape backup vs hdd backup
Well I know at least for my application the tape backup solution is being used for redundancy and save on cost. If a tape goes bad I have 6 more that are available to me which rotate on a daily basis automatically using a auto changer. If the hard drive was to fail on you then you would loose all of the data and have to start from scratch. Most companies also do offsite storage of tapes as well but I guess you can technically do both of these with the the external HDD but the automation process and expense would be greater. So I would say that its a matter of preference/expense requirements. Here is a picture of my setup which works great for me... *Windows box's back up to a 250Gig HDD on the local Amanada server over the network using samba. *Amanda backs up the local partition *Linux boxes backup directly using the amanda client This way I do not have to restore my windows backups from tape unless I need more the the last days of data. Helps save time for me at least.

Problems restoring files with amrecover on my backup client!
Hi list,
I have a small problem when I want to restore from
my DLT tape.
When doing the backup I
don’t see any errors (only one warning: driver:
WARNING: ignoring holding disk /space: No such file or directory)
When trying to restore
a file I got this:
amrecover> extract

tape drive /dev/nst0 on host npdev.
The following tapes are
needed: NP_TEST-00
Restoring files into

The fact that the tape can be removed from site for secure storage, and even removed from the use rotation for long term storage recovery and archival maintainance is probably the tipping point. I used tapes for several years, but as a home user and almost retired, the cost of replacement drives when they wear out, along with the relative lack of dependability of the only affordable tape format, DDS2, finally tipped me over to useing a 180GB partition on a seperate 200GB drive for my home useage. On that drive is /var, swap, and /amandatapes. /var is on a seperate drive here so I have a log if the main drive suddenly goes read-only. Its probably a kernel bug, and was, but its happened here. I run bleeding edge kernels most of the time, 2.6.11-rc4-RT-V0.7.39-02 ATM. And while the life of that drive may well be limited, I do expect 2-5 years service out of it since its mostly spinning 24/7/365 with a powerdown maybe once a month because something I did crashed or I'm changing hardware around, and that also exceeds the demonstrated life of a much more expensive DDS2 tape changer that I still had to fool with 2x weekly reloading the tape magazine. So far in about 6 months usage (that knocking sound you hear? Me, knocking on wood :) the only glitches have been setup and wrapper script glitches because my scripts also save the index and configuration data, appended to each "tape", so that a totally bare metal recovery can be made to a freshly installed drive should the main 120GB drive fail. After about 6 months amanda has finally come into 'balance', and the last 3 tapecycles have been hands off except for picking up the report from the printers output tray the next morning and stacking it on that pile of paper, and the occasional removal of the expired reports from that stack. I haven't figured out a way to make them self-destruct yet :) And thats my $0.02 take on it. If I could afford tape, I would use it, but at a cost well exceeding that big hd's cost a year for drives and tape, its out of reach of a SS recipients budget. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Oh oh, samba. Because of missing time fields in a samba (windows

For a typical system today, you need /space to be measured in
gigabytes, with a relative small percentage held in reserve for
incrementals. But with samba, you won't get incrementals even if it
says its doing a level 4 because every file will be considered new
every night.

Thats how much space is used between files on that drive. It probably
doesn't use that much, 32k would be typical, but thats what the math
spits out.

Let's hope your (single) backup disk doesn't die together with your other

Chuckle... While its possible Geert, there is a 1500kva, about 80 lb,
ups in the system. For obvious reasons, it sits on the floor. If it
dies, everything is gone but the telephone and overhead lights, it
all runs on one wall plug with a 500j surge arrestor thats even tied
into the phone lines. I've had no more surge related problems since
rigging it all out of one wall plug that I pulled and made sure
everything was tight in before I started. (actually, I pulled them
all, looking for the real feedline from the breakers) The operative
theory is that when lightning walks about, this whole room bounces in
unison & there aren't any other pseudo grounds to mess it up. This
house was built by a contractor who studied at the Hercules School of
(powder house) construction, where more than 1 nail per board is
frowned on. And in 1974 when this was built, West Virginia hadn't
yet imposed any electrical codes that had any great resemblance to
the NEC, so I've been trying to bring things up to speed, supplanting
a 60 amp rated pushmatic main breaker box with a 200 so I could get
power to a workshop just a year ago. *Most* of this place would pass
a 1998 inspection now I think. At least thats the date on my copy of
the NEC. And fortunately, its all copper. After having alu start a
fire a couple of times, when I find that stuff, it comes out if I
have to pull it out with my pickup. That would be messy, but
considering the alternative might be a box for my charred remains,
worth the effort.
The only thing that ruins the single point reference is the cat5
strung all over the place, with one piece even strung overhead across
the back yard to the workshop building, and at the instant, one to
the basement where the box I'm going to run my micro-mill with is
sitting on the pool table while I intermittently work on a driver for
the I/O card I'm using. Right now I'm waiting on a box from Herbach
& Rademan with some different stepper motors for that project, the
ones I first bought are too slow, and a bit puny.

stuck with amrecover
Hi list, I am stuck with amrecover. I want to recover data from my tapes. On the backed up client (the host from the disklist file) I run amrestore. I get the following error message: AMRECOVER Version 2.4.4p1. Contacting server on localhost ... amrecover: cannot connect to localhost: Connection refused I also tried #amrecover -C myconfig -s IP_OF_THE_BACKUP_SERVER I receive the same message. How can I restore my backups? What do I do wrong? ddaas

Thomas Løjmann Jørgensen wrote: How do I rewind the tape? I used a pencil: find a hexagonal pencil, stick it in the left whole, and now carefully rewind the tape by turning the pencil around. When you get used to it, you can rewind a 125m tape in less than a day. If you happen to use virtual tapes, then you need a virtual hexagonal pencil. Rewinding virtually does not take as much time, luckily. There are devices where you put in the tape, and that device rewinds the tape automatically. (I'm still amazed how small the pencils are they use inside.) Such devices do work on Linux too, and you have to issue silly werds like: "who am i", or "mt -t /dev/st0 rewind". Restoring with amrecover can be slow when needing to skip over all the junk in the beginning of the tape, so I used to position the tape just before the image to extract. For that you need to "fast skip forward" the tape. With a pencil I could fast-skip-forward a tape in less than 6 hours. But I'm a veteran. Practice helps here. Another option is to tell Amanda to rewind the tape and to fast-skip- forward the tape. Amanda also needs silly commands like, "vi amanda.conf", "", "", "o", "amrecover_do_fsf yes", "ZZ". And that ZZ means you can now sleep a little while Amanda does all the heavy rewinding and forward again. Being good in rewinding and fast-skip-forward, I'm not as good in verifying if I am doing this with the correct tape. That's why Amanda checks that too. The only language Amanda understands are again very cryptic, but that's how life is with Amanda: I always start with "vi amanda.conf", "kkko", "amrecover_check_label yes", "ZZ". Now, people say that all these words are explained in the man. But, Amanda being a woman, I tried to be polite and say "woman amanda", but I'm completely ignored and get yelled at "command not found". I gues that's what you got in reply too, isn't it?

Hi, Paul, on Dienstag, 22. Februar 2005 at 17:05 you wrote to amanda-users: PB> Thomas Løjmann Jørgensen wrote: >> How do I rewind the tape?

Rewinding virtually does not take as much time, luckily. I suggest a new chapter of the docs : could be "AMANDA humor" or "How things COULD be with AMANDA" ...

Backup over 2 tapes

My weeekly backup spans two tapes and I change tapes manually.

Re: Backup over 2 tapes
> My weeekly backup spans two tapes and I change tapes manually. My understanding was that Amanda didn't do tape spanning - if someone's figured out a way to do this, point me to do the doco :)
