Microlite BackupEDGE feils with error code 4.
Ulven
Here's the log:
Message Time = 2002-11-21 14:35:21
x BackupEDGE Release = 01.02.03
x Serial Number = demo1100
x BackupEDGE Expiration = Jan 18, 2003
x System Name = tourplan.haman.se
x WARNING: = Please Make RecoverEDGE Media
x Primary Device = tourplan:tape!tape0
x Software Block Size(s) = 64
x Hardware Block Size(s) = 512
x Volume Size(s) = (Unlimited)
x Media Usage = 9
x Number of Files = 0
x Backup Type [Status] = Master [FAILED - Status Is 4]
I've tried to set tape block to 512, tried to set it with -1
I can use dd to tape, and get it back again.. but when it runs for a while
it stops with this error code..
I have tested with 2 tapes now.
Anyone have a tip? i need a backup tonight, they are going to upgrade the
software that runs on the server..
I'll try some tape maintenence, retension, clean tape drive and so on while
i wait..... :-)

An Edge error 4 is "error writing to the archive device" according to my
Edge manual.
When was the last time you cleaned the tape drive? Are these older tapes?
Any chance the media was write protected, or that your tape drive has
occasional problems detecting write enabled tapes?
Call or Email Microlite if the problem continues.

backup/verify/restore on the thape, then i run a longer backup, and in the
end i got backup complete!
I also calculated the size of medium and put that into the settings.. it
might help..
Seems to work, but we might have to go to IBM and say that we want to
replace all 50 servers from Travan to DAT. Yes, we have set up about 50 ibm
netfinity servers, all come with travan tapes, all are having problems with
backup...

Yuck!
Travan technology sucks. Big time.
By all means, replace them with DAT. Or even SLR cartridges from
Tandburg or Exabyte, depending on capacity needs and budget.
SLR's are even more reliable than DAT's from my observations.
At least you have some confidence in the full Edge backup since it
bit-level verified.
If the 50 machines are to be in a locally attached server farm, then
perhaps you just need one machine setup as a backup station using an AIT
tape drive and back up the others over the network, especially if you're
using 1000baseT or ATM.
Tony Lawrence
And, assuming you are under 9GB, DVDRAM is even better. It's not fast
(3GB/hour or thereabouts) but the reliability and convenience cannot be
beat. As they increase the capacity of this stuff, I expect to see it
used more and more. http://aplawrence.com/Reviews/dvdram.html
BTW, I know both Microlite Edge and Lone-Tar support DVDRAM - not sure
about CTAR yet.

We want tapes, not DVDRam.. i'm sure DVDRam are good enough for people that
only need under 9GB with data.. but we think about company's growth.. been
bigger, more data you know.. :-)

Tony, if it is over 4.7BG, don't you have to manually remove the disc and
flip it? How are you going to do that in the middle of the night?

Or even the VXA from Ecrix, now part of Quantum. DAT form factor

You can sort of think of them as a removeable drive.
Since disks have the same type of access that Captain Kirk
discovered on the first voyage of the Enterprise and you don't have
to perfom a linear seek it has some definate advantages.
Define the problem, defined the needs, look at the wants and then
make sure what ever you acquire takes care of the first two. The
third is an added benefit.

I know: Everybody only wants restore, nobody likes backup...but no one
takes into account the thruput of the devices on restore...
If it's as low as 3GB/h then a retore of only 90GB would last 30 hours
(And a juke box if the media can't hold the 90GB)
Almost an entire weekend...but "fatal error" occurs
monday mornings...
SLR can do more than 5MB/s..10MB/s IIRC, 18..36GB/h
The above mentioned restore lasts only approx. 2,5...5h(!)
less than one night...(if the disc, cpu and file system is fast
enough to write that fast, sustained!).
LTO seems to be faster(currently) and bigger. But i don't like the
imagination the tape is again and again torn out of the (single coil)
cartidge...
Those SLR cassettes have a genious simple mechanism,
the tape stays always inside the box...

Happy journey ;-)
Tony Lawrence
Yes, but DVDRAM capacity is going to increase also..
Tony Lawrence
4.7gb uncompressed. With, compression, depending on the data sets, you
could actually get more than 9GB, but that's what I see in typical mixes.

I agree on this one. Historically, HD capacity and tape drive capacity
toggle with each other to stay in sync as far as capacity goes. All I
have to do is remind myself what a big leap it was going from 5.25
floppy to 3.5 floppy. 80Mb HD to 1Gb was a big step back in the old
Altos days. It keeps getting faster, smaller, with more capacity.

You've mentioned VXA and DAT in the same breath before. Let's
clear up some possible misconceptions....
Exabyte VXA (formerly Ecrix) is _NOT_ DAT form factor or DAT
compatible. It cannot read DAT tapes. DAT/DDS is a 4mm device.
The VXA-1 and VXA-2 use the 8mm form factor shared by...
o The original Exabyte/Sony 8mm drives,
o Exabyte Mammoth and M2
o Sony AIT-1/AIT-2/AIT3
While the data formats are incompatible, using that
form factor makes sense since the original founders of Ecrix
were ex-Exabyte and had all the right contacts in the 8mm world.
The VXA-1 and AIT-1 are excellent value propositions in the
"bigger and better than DDS" marketplace. Both have upgrade paths
to the next step, although I like the Sony handling of those
steps better than the Exabyte.
Exabyte markets the VXA series as a "DAT/DDS replacement" not
as a compatible device but as a next step up device.

Only matters if you fill a tape.
I haven't heard back from you on my suggestions/requests in
private email. Is this because things are working now?

Full system restores are usually more restricted by the write speed
of the hard drive than the read speed of the tape drive.
Partial restores are handled by Quick File Access.
Here's the summary of last night's backup on my main server.
(Currently using a Sony SDX-700C AIT-3)
FILES: 205713
Total DATA: 30.042Gb (Gigabytes)
Actual Tape Data Written: 30.095Gb (Gigabytes)
Elapsed Time: 47 minutes 26 seconds
Data Transfer Speed: 11389901 bytes/sec ( 651.7 Mb/min)
Here's how long it took to restore a file 5MB from the end of
the archive on that device using Quick File Access
(we call it Fast File Restore). This includes label check,
index check and rewind times.
mlite:root:ttyp2# time edge.restore -f tape0 /unix.test
edge.restore: notice: getting archive information
edge.restore: notice: beginning restore
edge.restore: notice: wd for restore is '/'
Reading Label From Media
Setting Tape Blocksize/etc.
Resource Access Started
Opening Communications with Device
Data Transfer In Progress
x ./unix.test
Operation Finishing
Resetting Tape Parameters
edge.restore: success (1 files)!
real 2:04.09
user 0.23
sys 0.51
Each media type is different. 4mm and 8mm formats
tend to be faster than SLR formats at QFA.

Well, the concept behind LTO and DLT is that by spooling out you
can have a larger tape in the same physical space as having to
use two reels. But it works quite well, and is time-proven.
LTO/Ultrium is about the fastet device we have in our lab.
The H-P Ultrium 230 can technically back up at around 2GB/min,
but we don't have a machine that can feed it that fast. It also
has very quick QFA.

Then you want to spend the extra money on highly reliable devices and
software that takes advantage of their diagnostics capabilities in order
to be able to head problems off at the pass. It also helps many newer
tape devices are "self cleaning" and you only have to insert a cleaning
cartridge on rare occasions.

Perhaps you need to make one small change to your source Tom?
:-) :-) :-) :-) :-) :-) :-) :-) :-) :-)
11389901 bytes second is 651 megabytes/min not megabits/sec.
Big B vs little b.
I've responded to others when they say they get speed
of 500mb/sec that I can type faster than 500 milli bits / sec.

Woops - I swore the first time I saw them - when they were first
introduced it was the same size as the DAT. They were pushing it
against DAT so I got the wrong impression.

I have got it to work, but many tapes failes, i have to run some small
backups on tapes, then longer and longer backups, in the end i got a full
backup of the server.. :-)
I'll wait and see for some days, try to do the same on the rest of the
tapes.. i'll get back to you if i have more problems!
Thanks for all help and info.. i've learned alot!
Cheers!
