Full backup

Yeah sure i can fire up winscp and do it that way, but since we already spend alot of time inside the DWC i think it's unnecessary having to use another tool to do the same job.
-
I'm not sure, but I think part of the limitation with getting the DWC to do heavy file processing is the relatively weak CPU which is not suited to the task, plus the waiting for SD card reads and folder recursion.
I think it's impressive that it can do a full folder download as a zip file. Maybe that changes with the Duet 3 and the single board computer since those tasks then become trivial, but for now FTP really is best way to do it at the moment.
But I totally agree with your request. It would be great to have an automated backup and restore option built in.

True, i don't need the ability to compress it before downloading either. But a function to at least download the whole contet of the sdcard would be so nice.When/if something goes titsup like a sdcard corruption or the board dying i don't need the ability to upload/restore it from the DWC. But if i atleast have a full backup laying there it makes the recovery job so much easier. Compared to either downloading it via FTP or pulling out the card and putting it in a PC (getting the card out means having to disasemble the whole board, because my enclosure don't have access slots).

wget is pretty simple:
wget -X /gcodes -r ftp://10.10.0.169/*downloads everything except the gcodes folder into a 10.10.0.169 folder locally.but yes, it'd be a nice to have feature in the DWC, but while you wait
-
@bearer Never used or heard of wget before so thanks for the pointer
Would still be awesome with a backup utility though
Don't know how into networking HW you guys here are, but take the Ubiquiti UNIFI/CloudKey setup. The CloudKey does a backup of the entire sdcard content at a set time intervall. That way one atleast have something to revert to if something goes horribly wrong. Dosn't help much if the sdcard f's up. But it's something, and the backup could be stored in the /sys/ whos's easily accessable for if one want to fetch it. -
add cron or a scheduled task in windows and you have regular backups. toss git in there and you have revision control, potentially offsite with bitbucket/github/whatnot.
might not be a one-click solution, but you only need to set it up once.
-
Well you can down load the whole sys folder and each macro folder from the DWC. So that's pretty much all you need for a recovery.

I didn't think the duet was doing much of the leg work with regards to the website. I thought that the web page files were served to the browsing computer then they ran on that computer, commumicating with the duet using gcode, ftp, and maybe telnet?

@doctrucker Right, but to packup the files into a zip file and send it to you has to be done by the Duet.

What happens with the existing backup of /sys and /macros is that DWC downloads each file individually and then zips them up.

@dc42 ...and the processing is done on the remote computer rather than the duet right?
That's how I understood it anyway. All duet is doing is serving individual files to the remote computer.

Ah I see. In that case, would it be possible to download the entire contents of the card and zip it up in the same way?
-
Possible, it's just a feature request for DWC as far as I can see.
I agree it would be useful!

Until this is implemented, going to the 3 places for gcode, system, and macros, then check all files and right click download zip, will be a yield a fairly complete protection of invested work.

and /menu if using 12864 display.
I'll stick with wget, if it gets a http url to hit instead that gets all the files, great, but ftp will also work as is.
-
Also, just verified in github that DWC is pulling individual files from Duet, and zipping them on the browser (dwc) side. As everyone was saying above. Definitely works this way.
DWC is using a unique service call, namely "rr_download,name=", so that it can get text or binary or whatever and add them to the zip.
Therefore, implementing this is a matter of adding a button somewhere, adding code to 'walk' the entire directory tree of the SD, and the body of that code would be identical to what zips gcode or macros or whatever today. Absolutely no changes to Duet/RepRap firmware needed.
Easy for Chris, and/or if there is enough commentary, I could give it a shot, and do it so that Chris can later pull it on git.

And Display if you are using a Duet Maestro.

Recursive wget (and probably curl, automated browsers and many download managers) would also work great with http. Almost certainly better since the protocol is far more sane than ftp. All that would be required is some url with an html page with one link per file. Or one page per directory for a whole tree.
Something that looks like the view you get when opening a directory or a web server served directory. Especially if you leave out sort columns or parent directory links so they don't need to be filtered out from the spider.

@xtl FYI, I'm using this to backup my printer:
wget -r -nH ftp://username@myprinter.local/{macros,sys,www} -
A recursive GET followed by a git add/commit would give you a pretty nice rolling history along with backups.
