bare metal: yes, this implies a better feeling.

i am quite happy with the backup function (whole disk) of FOG and FOG generally.

the only thing that i am missing are tools to make the creation of backups easier.

Hello George1421,

• 1.) NAS as FOG node
  This is a good option.

• 2.) FOG on VB (virtual box)
  I’ve pondered your suggestion that there are better ways to run FOG than on a virtual machine.
  And I suspect that I will set up FOG on a real computer with two hard drives (FOG, IMAGES) in the future.

• 3.) Fog as a backup
  I use FOG to do backups and not store pictures on computers.
  I am missing some tools that would help me with this.
  For example, to make backups of a group of computers.
  If I want to back up multiple computers, I have to set it up separately for each computer.
  Am I missing something here?

Hello everyone,

I currently have a Debian system running a VirtualBox.
In this VirtualBox I installed FOG on a virtual machine.
I wanted to have a separation between the FOG system and the IMAGES. So I use a second hard drive, which is mounted as a virtual hard drive in the FOG system and on which I save the IMAGES.
Somehow I have a bad feeling when I think about saving the IMAGES on a virtual drive.
Instead, I think about how I can save the IMAGES on a real hard drive?

Do you have any suggestions?
What could work?

Any ideas are welcome.

hello sebastian,

thanks for your reply!

i have taken a backup of both HDDs with “ddrescue” too.

Why did you use the resizable image type?:
to be honest: I am using FOG for backups and have captured a lot of images using the default settings - and i had never troubles with it. the other computers were using windows-7 oder 10, and also did not have RAID.
so, in this case, while capturing windows-xp with raid, i did not think about this.

because i had never to deal with this computer and also not with RAID all of this seems to me a little bit odd.

i guess i will have to test around a little bit to get more information.

hello george1421,

thank you for your support. its a “3ware” raid controller.

its possible to use FOG to clone these disk structures but you need to know ahead of time

yes, i did understand this later

sorry for going to ask maybe some “dumb” questions now , but i am really a little bit nervous about this situation. its a very old system (win-xp, so over 15 years old) and it contains very important data. but i could create a backup - so thats the good news.
i am trying not to miss something, which could effort a lot more work.

a.) what if i do remove the wrong hdd and reattach it again?
e.g. i do remove the sdb, i start the computer, noticing this mistake, turning off the computer, reattaching sdb and removing sda.

do i have to worry about losing data?

b.) hdd on port 0 not in use?
what does this mean?
is this the reason why i do get he message about the “missing os system”?

because i can see the sda if i start a live-sytem and can also create a backup with clonezilla.

c.) is it a normal behaviour of RAID-1 not to boot if the mirror is broken?

should this behaviour be bein expected, or could it be also posible to boot a system even if the mirror is broken?
e.g. the mirror was broken a long time ago - but was not recongniced.
so the system was running in a “degraded” mode.

thank you for you help!

hello,

i ve got the following situation:

i was capturing an image from a computer (windows xp) which has raid-1.
during this process an error-message showed up, saying that some “bad blocks” were found, and i should try so save my data.
after this, the upload process did cancel and restart. after the restart it did start the upload-process again and ending with the same message of “bad blocks” and restart again and so on.

so i did cancel this task in fog.

when i start the computer now a message that “no os system” was found is showing up.

in raid bios-menu the message is shown that the array is downgraded.
this arrays consists of two disks.
the disk on port-0 is not in use.

i guess that maybe the “shrinking” of the partition did break the mirror in raid-1. but this should not be the problem that windows-xp is not being found.

i still have the data of the image-upload-process in /images/dev folder.

my question:
how can i find the original size of the partition?
because it seems that after every restart and retry to upload the image the last (so shrinked) partition-size is being written to the /dev folder?

what else could cause the problem?
(of course, there are also the “bad blocks/secotrs”. but until the backup this seems not to make any troubles. )

i am in troubles and i need please some help
(and yea, i had never to deal with RAID)

thanks in advance.

greetings lakk

info:
when i click to “host-management” -> “Image History”,
the right date is being displayed.

hello sebastian,

thank you for your support!

i did run the maintenance commands as user “root”, but it did not help.

i will be in holidays for the next two weeks.

br lakk

thank you!

there is another strange thing that i have noticed.
the number of active tasks is not displayed on the dashboard:

in my opinion, this issues did pop up after i changed something in the virtualbox-settings of the gues-account.
there was a problem, that the captured images have not been stored on the sdb1 (VMDK) but instead as a snapshot on the host-system. so the snapshot was growing
and the host-system did run out of space.
i did get help in the virtualbox-forum and could solve this problem.
but it seems that since this time i did get this two issues:

• “no data”
• “number of active tasks is not displayed on the dashboard.”

but maybe it’s a coincidence.

i have noticed, that the new images which are being stored in /images belong to root.

i did change the folder permissions of this image to fogproject,
and restart the fog-server.
but it did not help:

hello,

unfortunately - i did upgrade to FOG 1.5.9-RC2.11 but i still have the same error.

i have installed fog on a virtual-machine (virtualbox).
host-system:

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 149.1G  0 disk

└─sdb1   8:17   0   1.4T  0 part       

i am using sdb1 as a vmdk-hdd, which is mounted on the fog-server (guest) as /images:

fog-server is installed on sda1 - sda5.
i did use this instructions.

i did try several captures but i still have the same issue.
Please help me with this issue. What could be another reason for this?
Is there something that could check to get more information?

greetings lakk

ok. thank you for your support.

(ehm, how/where can i markt the topic as solved?)

hey all!

my situation here is:
i can capture an image from a computer. and this captured image is also being displays in the “images management” menu (site):

its also possible to deploy this image

but when i open the “host management”, its is written “No Data” instead of a date when the image was captured:

any ideas?
