Excellent. What are the exact FTP commands you're using? Of course, I'm sure you're testing on Linux. It would be cool if someone else could follow up and make sure the same command work with the Windows FTP command-line. They *should* but of course, who knows. It's Windows after all. I'd do it myself but I'm doing other stuff today...

Entire disk:
GET /dev/hda
Any single partition, same command, change hda to hda3 or whatever (I don't remember which partition holds the dynamic data).

So the entire disk includes all partitions including the dynamic data?
so an example of an entire disk backup for a two drive player is:
GET /dev/hda
GET /dev/hdb
I assume you have to put the FTP software into binary mode first... or at least that's what you'd want to do on windows anyway...
To restore, what would the PUT commands look like?

Yup, that's all correct.
And going the other way is just a simple PUT command. For example, these two commands copy the drive to a PC, and then write it back again (pointless in itself):
GET /dev/hda junk
PUT junk /dev/hda
Those just use "junk" as the name for the file on the PC side. Or one could omit that, and the two lines become:
GET /dev/hda
put hda /dev/hda

Quick question: Do you need to put the player into RW mode before doing the PUT commands?

No. It's safer to leave them RO. Even safer to unmount them altogether, but that's not really possible.

Actually, Mark, will the NFS server work if the disk has just been replaced? And will it understand what /dev/hda even is? It is a filesystem construct, after all.
And, in the case of a restore onto an "old", already-built disk, is Hijack going to panic when it notices a filesystem inconsistency?

In the instructions I'm writing, I'm making sure that before someone does a PUT to restore the disk, they've done a full disk rebuild, software install, and hijack install, so that the player is fully working again.
Although I have a related question: Should the player software be exited out to the shell prompt before doing a full-disk PUT operation? And if so, is there a hijack command that'll do that for me via the FTP command-line interface, similar to the SITE RO and SITE RW commands?

It would be best to stop the player app while doing the image restore, but it should work regardless. I think Bitt once figured out the correct FTP SITE EXEC for that.

Okay, the updated FAQ entry is here. I'm a bit brain-addled at the moment and can't bear the thought of fact-checking and typo-checking that entry right now. So if anyone notices any errors, please report them here. Thanks. Doug, your one-click backup/restore solution is now just a batch file away. I think you know how to write the batch file at this point, you've done FTP scripts before, right?

This:
Code:
SITE EXEC kill -2 `ps ax | grep player | grep -v grep | awk '{print $1;}'`
might work, but don't quote me on that. Someone test it first.

Yes, like the ones I run to use the player as a file taxi.

Cool, thanks Bitt. Okay, that's a pretty complicated little command, there. I understand why it has to be complicated, but for now I think I'll leave the FAQ entry as-is, where it says to kill the player via the shell prompt with the serial cable.

Well, if you're going to do that, you probably don't need the other grep either. Code:
SITE EXEC kill -2 `ps ax | awk '/player/{print $1;}'`

awk isn't included in the default player image, though.

Well, unless you anchor the awk pattern (not able to connect to my empeg right now to see the output of ps), you will end up selecting the grep line too...

ISTR it working at some point. Maybe it's in the developer image?
Hmm, all in bash. Tough one. It'd help if bash wasn't a pile of crap (they really need to stop claiming it's ksh-compatible).
Code:
SITE EXEC kill -2 `set $(ps ax | grep player | grep -v grep); echo $1`

If you put the first letter of your search string in square brackets you don't need the grep -v. (The process table will show the brackets but grep parses them as indicators of a class that consists of the lowercase p.) Code:
SITE EXEC kill -2 `set $(ps ax | grep [p]layer); echo $1`
