The best way to back up an Amiga?

I have an A1200 with a 4gig CF card as a hard disk. I would like to back it up every week or so to either another CF card (PCMCIA port) or to my iMac via FTP.

The problem with the PCMCIA card, aside from being insanely slow, is that I have to take the bbs down for the duration of the backup.

The Problem with FTP is I don't know if I will lose anything if I ever have to restore them like file name length truncation or loss of protection bits or whatever.

One workaround that takes a lot of manual labor is zipping up all the dirs on my DH0: and FTP'ing those over but that is very time consuming.

Are there any other options? I have a DH1: that can easily hold the contents of the DH0: that I need to backup, maybe a backup utility that backs up to DH1: in a file that I can then FTP to the iMac?

Thanks in Advance!

LHA utility is enough mate.

Just open a CLI and type:
Code:
1> DH0:
1> lha -aezrx a DH1:backup.lha #?
That will create a file called "backup.lha" under partition DH1 (assuming the partition you want to backup is partition DH0) maintaining all protection bits etc.
The archive is not compressed so it will be rather large. If you want to make it compressed also just replace "z" with "Z" in lha options of the command provided.
Then of course you can transfer the one lha file via FTP or any other way anywhere

To restore the archive anytime just use the following command:
Code:
1> DH0:
1> lha x DH1:backup.lha

Cool, just tacked that on to my weekly bbs maintenance script! I am probably going to go with the compressed version.

Thanks again!

You might want to do a list lformat type thing as well. (eg: "list dh0:#? all dirs lformat "makedir backup:%n*nlha %n -aezrx a backup:%nbackup.lha" >ram:s", then just execute ram:s) That way you could have smaller archives, split by directory, instead of one huge one. I have a 40GB drive that I back up to a fileserver using SMBFS on occasion, and I've noticed LHA tends to slow down the bigger a file gets. (could be more SMBFS than LHA, but LHA seems to want the whole archive in memory before dumping it to a device, though probably only when actually compressing it)

(Using the same method with a "delete %P%N" and "p=thumbs.db" has proven extremely useful for post windows photo viewing purposes, too. hehe)

EasyADF will allow you to backup whole partitions or directories easily into a LHA file with a few clicks. Here is the tutorial:

http://www.amigakit.co.uk/support/easyadf-backup.php

This may be useful for users that want to backup their entire System partition to another hard disk or Compact Flash card for safekeeping.

Fantastic everyone, thanks! I have easyADF, never thought to try that.

@Watertonian, yeah it does seem to be slowing down a bit, fortunately I have a decent CPU and 128 megs of ram, though it doesn't appear to be hogging the ram right now. I may go this route though so thanks!

Looks like I have the older version that came with my PCMCIA -> CF kit I purchased from you guys back in 2008. Version 0.181 I think. I may have to get the update. Can I purchase it and download it instead of having you mail a floppy all this way?

You can have a free version emailed to you- just send us a Support Ticket and we can arrange for the update to be emailed.

Thanks!

Apologies for reviving this old thread, but just ran a google search for information relating to backing-up a hard drive, and up came this thread.

I bought the CF adaptor kit from yourselves a few months back, but have never used it as I also bought the network card.

Anyway, the software's working a treat, and the Amiga's currently sat here backing-up.

Thanks for the help!

Glad you found it useful :-)

In the next version I may add a Backup Scheduler.. any features you want to see on it, let me know.

Useful? It's superb! It seems to use LHA differently to Directory Opus 4, as DOPUS gets 'really' slow as the archive gets bigger and more files are added. The Amiga Kit backup rockets through.

A backup scheduler. That'd be fantastic.

Perhaps an option to choose archive types (LHA or ZIP) would be nice.

LHA is mighty slow, I wouldn't recommend it (I know, I been through this route once and it was painful).
My advice to you is to get your card or drive to a PC and back it up to a folder in your PC using WinUAE.

Slow is a relative term.
If your CF card is inside your A1200 (i.e. You don't have one of Kipper2Ks neat adapters that puts the CF card right above your PCMCIA slot) and you have a LOT of stuff hooked up to your A1200, and you don't really have a good place right there to open the 1200, etc etc etc...

Then, just getting to the CF card might be a hassle, and you have to put it all back together..

Whereas, just firing up a program and letting it run while you play a bunch of games on your Vectrex so you don't even notice...
That can be kind of nice..

LHA is slow when it's compressing, but the command line mfilos provided creates an uncompressed LHA, which is much faster.

An update to EasyADF is being developed now, I will consider adding Zip support to it.
