@heix75 Thanks a lot for reply!
I use a medical lab program that stores clients data and examinations results almost all day. Of course I take incremental SQL backups.
So if something breaks I would like to have a recent PC backup to only restore SQL.
I used Macrium for that and now I use UrBackup which is open source but not widely used and I wonder if Fog would be a better solution.

I want to take full backups of 5 Windows 10/11 PCs at work using an open source project. I intend to schedule the backups between late night and morning before we open. I want to take backup of my main PC every night and backups of the rest PCs eg once a week.
I was using fog according to this scenario many years ago without any problem.

Why is it not suggested to use fog as a backup tool? Everyone suggests Clonezilla. Isn’t fog like an automated Clonzilla without the need of manual backups using a usb stick regarding the backup function?

Thank you!

At he time I have a multiboot PC: Windows 11, Gentoo, Linux From Scratch.
I tried to experiment with fog, so I installed it on an old Intel NUC with 256GB disk space and debian 12 which is no enough even to capture my smallest OS LFS. How much disk space do I need to store the images? Would you suggest to extend this NUC or get another PC?

OK I changed the repositories to strech, updated and now version of dnsmasq is 2.76.

I edited /etc/apt/sources.list and added
deb http://ftp.de.debian.org/debian testing main
then

apt-get update
and then
apt-get install dnsmasq/testing

~$ sudo apt-get install dnsmasq-base/testing
[sudo] password for hk:

How can I get rid of 2.72? Why windows xp pc boots normal but then goes to windows instead of capturing image?

~$ dpkg -l | grep dnsmasq

I just followed this guide: https://forums.fogproject.org/topic/12796/installing-dnsmasq-on-your-fog-server
. The only thing I put is the IP of the server where needed.

Thank you!

Thank you, I installed dnsmasq on Debian 8. Version was 2.72 by default and then I installed successfully as the terminal said version 2.80-1. But with
sudo dnsmasq -v it still says verson 2.72 is installed, I guess because version 2.80-1 is from testing repository.

Unpacking dnsmasq (2.80-1) ...
Setting up dnsmasq (2.80-1) ...
[ ok ] Starting DNS forwarder and DHCP server: dnsmasq.
hk@debian-server:~$ sudo dnsmasq -v
Dnsmasq version 2.72

This massage about 2.72 version shows even if I uninstall dnsmasq.

I still have the router as DHCP server.
When I create and execute an instant Capture task, Windows XP pc boots but shows message:
TFTP.
PXE-T01: File not found
PXE-E3B: TFTP Error - File not found
PXE-M0F: Exiting PXE ROM.
and then boots to windows.

I use the same FOG installation as I had with dd-wrt router and dnsmasq in router.

Any help?
Thank you!

I have 2 PCs (1 windows 10, 1 windows xp) connected on a LAN to a FRITZ!Box 7590 router. I Can I use fog to take images from my PCs with this router? Can I put pxe boot options in settings of this router?
Thank you!

As I said everything works great! Thank you again for great support!

I re-installed fog and everything works fine!

Sebastian, sorry for confusing you. The log above is just from Scheduler restart, without any task. I upload here a new wol.pcap where you should see a packet from an instant task.0_1459415578972_wol.pcap

Yes of course. WOL was working in both PCs with undionly.PXE. After I put the 12 lines in DNSMasq it does not work with fog. But I can wake up my PCs from the routers interface.

I use fog trunk 6957 and Firmware: DD-WRT v24-sp2 (02/04/15) mega

The log is (times are correct):

Thank you Sebastian!
There is big progress! :

I opened both (UEFI, BIOS) PCs and got into PXE menu in both PCs. I successfully fully registered them both. With Host EFI Exit Type=REFIND_EFI UEFI PC goes into windows after PXE exit. BIOS PC goes into windows after PXE exit without putting something in Host Bios Exit Type.

But there is still some problem: fog can not boot both PCs. Scheduled or instant tasks don’t start. Time is correct, I put local time in General Settings, I restarted fog scheduler with

sudo service FOGScheduler restart

but nothing happens.
Thank you again!
