[2008 R2] Help with backup

Hello,

Could someone help me understanding what I'm doing wrong with 2k8 r2 backups ?
I'm trying to backup a folder's content into a destination located to an external USB drive.
Folder to backup : e:\data
Target folder : g:\target (where target will be the date in yyyyMMdd format)
If I start powershell and type :
wbadmin -backupTarget:"g:\target" -include:"e:\data"
then I end getting an error message complaining (I translate from french, so sorry for errors) that :
"The specified backup location cannot be found or is not a valid backup location"
But, If I type :
wbadmin -backupTarget:"g:" -include:"e:\data"
then, it works fine - but, then, I cannot have distinct backups for each day.
I browsed MS boards and technets, but couldn't find any helpful information on this. And google was anything but my friend either.
Any idea about what I'm doing wrong ?

Many thanks,

J.-L.

 

Hello,

Fine. I give it a tray, then I come back.

Thank you.

 

Me again...

I modified the script to match destination requirements :
------------- Begin script -----------
$jour=get-date -uformat %Y%m%d
$vol="\\m20sewhq01\g$\SVG-Quot\"
$dest=$vol+$jour
mkdir $dest
wbadmin Start Backup -backuptarget:$dest -include:"D:\Horoquartz" -vsscopy -quiet
--------------- End script -----------
This time, I get another error that says approximatively :
"Unable to achieve requested task because of system file limitation"
However, the folder 20130502 is correctly created on G: and, moreover, content has been added to it, as one can see in attached file List.txt.
I redirected the output to a file I attach here - guess it won't be of any use... -.
This 2k8 r2 is getting me more and more puzzled...

It's NTFS. But I don't see why it would be relevant, since backups only fail when I try to send them in a folder. If I do them at the root of the volume, they systematically succeed.
Seems not that logical to me...

Hello,
Just tested to be sure : the windows backup task itself behaves the same!
So, I created a script for daily-backups and one for monthly ones (this one saves the whole server), all sending data at the root of G:\, and I'm going to see what happens.
Next step will be to check for what I cant retrieve this way, ie if I can only retrieve data from the latest backup, or also ones from a earlier backup.
Let's keep our fingers crossed.

Best regards,

Hello,

@ Mr 0x00 : compression is not enabled on the target disc ([right clic / properties / compress volume to increase free space] is unchecked, assuming that is what you mean). See below the 2nd part of my reply to cyberbot.
@ cyberbot : this software looks fair, though I don't think I will be able to have it bought before next year, as it wasn't budgeted.
As for the fact it only supports one partition per disk, I don't understand what it really means. I found an article on iTPro ([itpro.] [fr/a/creer-sauvegarde-windows-server-wbadmin/] remove all brackets and spaces) with a script that I slightly modified (and corrected some minor typos) as follows :
-------------------- Begin Script ----------------------
@echo off
chcp 1251
::SVG-Mens.bat

rem backup target UNC
set Target=\\M20SEWHQ01\G$

rem define date time variables for building the folder name
set d=%date:~0,2%
set m=%date:~3,2%
set y=%date:~6,4%
set h=%time:~0,2%
set min=%time:~3,2%
set sec=%time:~6,2%

rem files and folders to include

rem defining target folder like \\Server\backup\20091215_132532
set newfolder=%Target%\SVG-Mens\%m%%d%%y%_%h%%min%%sec%
echo Creating %newfolder%
mkdir %newfolder%

rem run the backup
echo Backing up %include% to %newfolder%
wbadmin start backup -backupTarget:%newfolder% -allCritical -vssfull -quiet

rem Clear variables
set backupshare=
set include=
set m=
set d=
set y=
set h=
set min=
set sec=
set newfolder=
------------------------ End Script ------------------------

Running this script worked fine : it saved my server correctly (at least, that is what it reported!).

Then I duplicated it and modified so as to get a different one for partial backups :
------------------------ Mods & add-ons ------------------
.../...
rem files and folders to include
set include=D:\Horoquartz,E:\HQSAUVE
.../...
echo Backing up %include% to %newfolder%
wbadmin start backup -backupTarget:%newfolder% -include:%include% -quiet
.../...
-------------------------------------------------------------
This time again, as I feraed it, it didn't work.
What I can't understand is why, with the same syntax, partial backups always fails as total ones always succeed (I didn't try full backups before, as I was focussed on the problem) ?

J.-L.
