A bit late to the party, but perhaps you could get something from
strings:

  $ strings /bin/tar | less

/lib64/ld-linux-x86-64.so.2
,crS
>gUa
librt.so.1
__gmon_start__
_Jv_RegisterClasses
clock_gettime
libc.so.6

(... and so on, but some of this crap might be useful for your
goal...)

I guess strings is rather easy to write in C, if you do not have
it. Or maybe even could be concocted using a bunch of shell and
pipes.

Re: Wanted: LTO-5 tapes (used?)

If Ethan doesn't want them
I'm morbidly curious what you would want for a drive and some tapes.
Also, where you / they are at so that I can guestimate shipping.


I am after LTO-5 as that is what my best drives are (untested of course, 
and they came from trash.. how bad could it end?)


Library after I got the LEDs installed. Need to get a dedicated power 
supply for them:

I've got it down on one power supply, and it can run on 1 PS with two 
drives and the logic board. No fibre channel switches or any of that.

I know a number of people that use LTO, some of whom use LTO-5.

LTO-5 has been recommended to me a few times, I didn't ask too many 
questions.  I thought it would be better to learn more about what it 
is, and about tape backup and archiving in general so that I could 
contextualize my questions and understanding better.


Fair enough.

As it happens, I'm now seriously looking into tape.  Off the top of 
my head I imagine the following things to be the potential attractions 
of LTO-5:


-   Is LTO-5 somewhat of the standard by which other LTO tape systems 
are judged?


LTO is a type of tape.  The 5 vs 4 vs 3, is the generation.  So LTO-5 is 
the fifth generation of LTO tape.  Newer generations typically hold more 
data and / or are faster to access.  Benefits of the evolution of the 
technology.



-   Is bang for the buck the primary attraction of LTO-5?


"bang for the buck" is subjective.  Are you talking raw capacity?  Raw 
Read / Write speed?  Seek time?  What?


I'm guessing that it's better $ per byte.

-   Is LTO-5 the best option when a priority is to use open hardware 
and open source drivers to interface the tape drive to the host?


I'm probably not qualified to answer that.

It's my understanding that many manufacturers make LTO drives (of 
varying generations) with varying types of interfaces.  I'm guessing 
that (some version of) SCSI and / or Fibre Channel are the most common 
interfaces.  With the former being directly attached to a host and the 
latter being attacked to a SAN that can be accessed by multiple hosts.


I did some research and got the impression that HP LTO-5 Ultrium RW 
3 TB cartridges are more-or-less the standard when it comes to the 
actual tapes.


It's important to know if you're looking at uncompressed / native / raw 
capacity.  Many drives and / or backup applications will (try to) 
compress data before it's written to tape.  It's not uncommon to see 
some claims of up to 2:1 compression ratios.  You might get this with 
text.  I doubt binary data will get it.  Your mileage may vary.


From my perspective, 3 TB doesn't seem like a huge amount of storage. 
Especially when, for example, a 12-disk array of 8-10 GB HDD's is 
hardly uncommon.  Am I completely misinterpreting the way that tapes 
are supposed to be used when making backups or archiving such an array? 
Obviously I'm not going implement an intricate differential or incremental 
backup or archiving solution until I've got full backups working properly.


My experience has been to use some sort of incremental backup strategy. 
Full backups of the entire data set usually take prohibitively long and 
can't be done in normal backup windows.  (There is an entire 
sub-industry for optimizations here.)


I would recommend you at least learn about the traditional grandfather, 
father, son backup methodology.  An alternate is incremental forever, 
which does one really big incremental (from zero) and then deltas 
between each backup run.


You probably want to do some reading about how tapes actually store 
sessions.  Specifically, can you continue writing to the tape after you 
finish a backup?  Can the next backup start writing to the same tape 
after the point that the first backup stopped at?  Or do you end up 
wasting tape.



Comments and opinions are well appreciated.


I'd suggest you look into something that can manage backups for you.  It 
is possible to do it yourself, with something like tar, but you will be 
doing a lot of manual effort.


That being said, I have rolled my own backups using tar and the raw SCSI 
tape device.  But I've been told I'm a masochist.  ¯\_(ツ)_/¯

Re: helping to clean out an estate - a lot of CRAY

[Ethan via cctalk]

I appreciate the multiple offers to digitize the tapes. I will try to get
back to everyone next week.  Maybe split the load? Looking for ideas here.
My only rule is both museums get a copy and post it for public use. I do
have a few requests for some of the original tapes.


I was one of the people that offered. I have pro decks, Composite + SDI 
converter, audio processors for volume maximization on spoken content, and 
a Blackmagic ATEM system for SDI to H264 conversion. Colo host and 60TB of 
disk at home, along with a 500TB LTO-5 library.


My goal is just to digitize the tapes, get the files to whomever wants 
them (plus archive.org), and then the tapes go to some collector that 
wants to hold onto the originals. I don't have physical room to store the 
tapes long term.


I have archived a lot of laser show content recently that is digital data 
stored on 3/4" umatic, Beta, and SVHS ADAT format. I've found that pro 
tapes have help up well but consumer tapes less so.

Re: helping to clean out an estate - a lot of CRAY

[Paul Anderson via cctalk]

Here is the update:

When I returned from VCFMW, I took my time emptying my minivan. It was
mostly empty empty when I learned of my friends death. A mutual friend put
me in touch with his brother because I was interested in some photography
equipment he had talked about selling me earlier.

When I got there and he found out I was into computers, I offered to buy
items from him. I have removed  THREE vans loads, and I probably have THREE
MORE to go. I sort (computer/non-computer) and load all afternoon, unload
and sort all night. I have sorted boxes of CRAY, all kinds of conference
and trade show material, monthly, quarterly, etc periodicals, and 10 or so
boxes fill of memos, research papers, sales literature, benchmarks, and
grant proposals. There are papers, etc. there from most major universities,
government agencies including Aragon natl labs, Los Alomos, CERN, ETC.

Basically, it could take months to go through everything. I would like to
got the CRAY items that I have found so far ( I look through all the boxes,
but might have missed some) which are now about 40 three ring binders and 4
boxes of packets and small items first. Also the periodicals that are
sorted would be nice to get out of my way. The more you want, the quicker I
can get it processed. Smaller lots might take longer.  Feel free to ask
questions or make requests. I'm sorting as quickly as I can.

I appreciate the multiple offers to digitize the tapes. I will try to get
back to everyone next week.  Maybe split the load? Looking for ideas here.
My only rule is both museums get a copy and post it for public use. I do
have a few requests for some of the original tapes.
