Digital BW, The Print

I have been looking into purchasing an external harddrive. My question is can 
you keep more than one connected and available at a time? 

Thanks.

Oops, just found my question regarding connecting multiple external 
harddrives had already been answered by Clayton. Thanks!

Hi,
thanks to all of you for your advice. I think your external options are the best ... but due to impecuniosity, I opted for a 160BG internal as I don't have USM2 for firewire. When I upgrade, I'll just transfer the drives into the new box.

You lot make my life a whole lot easier. Thank you all for putting up with my often dumb questions.

Long live the Digital BW list!!!

thanks again,
Richard

We all get there sooner or later. It's sad when you suddenly can't 
save a change OR the file!	
	As an ongoing solution, routinely transfer new files to a CD-RW. 
When the CD-RW gets full, make 2 CD-R copies of it on high quality 
media and store one of them somewhere away from the other one (so if 
fire or some other failure gets one, the other is apt to be safe). 
Clear the CD-RW and your hard drive and start again. 
	A CD-RW is not good for long term data archiving, but can be used 
multiple times for temporary storage. High quality CD-R (properly 
handled and stored) is much more reliable than any of the magnetic 
media, including hard drives. Best guesses run around the 75 - 100
year range. Long before that they'll be obsolete, and you'll have to 
copy them to the latest best thing.
	Or back up to DVD-R and make a second copy when it gets full. Even 
more robust media than CD, but can't be reused.
Good luck!

Jim

Jim;

Do you have any info supporting the above? I've been doing just 
that, but I haven't yet seen any numbers for DVD-R media anywhere, 
and I would very much like to.

Steve -- In a CD, the data dye layer and the reflective layer are on
the top / label side of the disk and more subject to physical and
chemical and light damage. Triple true in "bargain" disks. DVD has
those layers sandwiched is plastic. Hence more robust. 
Think floppy disk and you'll see that we mostly have to worry about
the media outlasting their popularity, and not real archival quality
like we're usually talking about here.
A related issue, worthy of its own thread, is my great fear that the
primary legacy of the digital photo revolution will be total disaster.
We've all heard stories of folks running out of their burning house,
leaving jewelry and heirlooms behind, clutching the family photo
album. The thing they can never replace. I see a huge demographic
trusting their priceless family memories to extremely transient media.
I reckon the fraction of folks backing up their digital photo
collection to reliable media is vanishingly small. ALAS!

Joe,

If you use xxcopy and a batch file, you can just click on a desktop icon and 
xxcopy will compare your backup and main HD's and just copy the ones that 
are not yet backed up. Dead easy. I use it for backing up various folders 
and drives on three networked computers. Ordinary xcopy can work, but may 
make mistakes in long names apparently. XXcopy prevents this and allows a 
multitude of options to put in the batch file.

XCOPY won't delete backups of files that no longer exist. Will XXCOPY?

Paul,

I think it is one of the hundreds of options, although I haven't used that 
one myself yet.
I use a simple set of options that show me on screen what it going on, such 
as

xxcopy E:\data\*.* I:\datacopies /BI /E /FF /Po0 /WE

or for copying to a networked computer

xxcopy E:\data\*.* \\home-2\maindata2\datacopies /BI /E /FF /Po0 /WE

I have about a dozen such lines in one batch file, and one of the above 
options stops each between each line and gives a breakdown onscreen on what 
it copied. Then a touch on the spacebar and it does the next line. You can 
run it completely in the background, but I still like to keep an eye on it.

I leave deleted files in the backup at present as a precaution, and just 
delete the whole backup if I run out of space, and let it copy the current 
files over.

It's free for one computer, but you need a licence for networked computers.

This is prompted by the discussion of xxcopy, which I have not used...

I use a program called InSynch -- a Windows program. With this, I duplicate all
my data files onto a backup set on a second computer via Ethernet. I do this as
a protection against hardware failure and (more likely) operator error.

A couple of times each day I click an icon on my desktop, and InSynch
synchronises the two sets of files without any attention from me, copying and
deleting files in the backup set as necessary.

I am a satisfied user, but have no other connection with this program. Read more

Peter,

Not seen it before, but InSync looks quite good for those who do not want to 
dabble with batch files and command lines. XXcopy is certainly not for the 
faint-hearted!
