Server 2008 Std R2 Backup warnings

Question

Hello,
I'm having a problem for a while now with Windows Server Backup (with VSS). I don't really know when this started.
The thing is 3 of 5 partitions are backing up with warnings. Process can't backup some of the files which are:
Błąd podczas zapisu przy tworzeniu kopii zapasowej pliku F:\System Volume Information\SRM\quota.md: błąd [0x80070020] Proces nie może uzyskać dostępu do pliku, ponieważ jest on używany przez inny proces.
Błąd podczas zapisu przy tworzeniu kopii zapasowej pliku G:\System Volume Information\SRM\quota.md: błąd [0x80070020] Proces nie może uzyskać dostępu do pliku, ponieważ jest on używany przez inny proces.
Błąd podczas zapisu przy tworzeniu kopii zapasowej pliku E:\System Volume Information\SRM\datascrn.md: błąd [0x80070020] Proces nie może uzyskać dostępu do pliku, ponieważ jest on używany przez inny proces.
Błąd podczas zapisu przy tworzeniu kopii zapasowej pliku E:\System Volume Information\SRM\quota.md: błąd [0x80070020] Proces nie może uzyskać dostępu do pliku, ponieważ jest on używany przez inny proces.
Process can't access these files because they are being used by other process. As I found out these files are disk quota files. I also read that I may backup them manually but I don't like that idea.
I tried disabling Antivirus software, deleting excludes from backup, changing time of backup. Nothing works.
I got 2 questions.
1. Will these errors make restoring backup impossible?
2. How I can fix this?

Hi Filip,
For this when you try to backup your file you can use the following :-
1. While backup from one drive exclude the following " $recycle Bin , System Volume Information, Quota temples"
2. After completing the backup of all data from your HDD you can also take a system state and Bare Metal Recovery.
For backup all share NTFS permission and Quota Details you can also backup the registry. Follow the steps for Backup :-
To backup share permissions, export the Shares registry key.
Open Regedit to the following location:
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares
Right-click the Shares registry key and select Export. Give it a file name such as
shareperms.reg.
When you want to restore the permissions, double-click shareperms.reg to import it back into the registry.
Use the Reg tool to backup the registry key from the command line:
reg export HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares shareperms.reg
If you need to restore it at some point, just run:
reg import shareperms.reg
Backup and Restore of NTFS Permissions
Use this command to backup NTFS permissions:
icacls d:\data /save ntfsperms.txt /t /c
The /T switch allows it to get subfolder permissions too. The
/C switch allows it to continue even if errors are encountered (although errors will still be displayed).
Use this command to restore them:
icacls d:\ /restore ntfsperms.txt
Note that in the command to save the permissions, I specified the target folder
D:\Data, but when I restored them, I specified just D:\ as the target. Icacls is a little funky like that, and here’s why.
If you open the text file with the exported permissions (ntfsperms.txt in the above example), you’ll see that Icacls uses relative paths (in bold below). Underneath the relative paths are the permissions for the folders in Security Descriptor
Definition Language (SDDL) format.
data
D:AI(A;ID;FA;;;BA)(A;OICIIOID;GA;;;BA)(A;ID;FA;;;SY)(A;OICIIOID;GA;;;SY)(A;OICIID;0x1200a9;;;BU)(A;ID;0x1301bf;;;AU)(A;OICIIOID;SDGXGWGR;;;AU)
data\folder1
D:AI(A;ID;FA;;;BA)(A;OICIIOID;GA;;;BA)(A;ID;FA;;;SY)(A;OICIIOID;GA;;;SY)(A;OICIID;0x1200a9;;;BU)(A;ID;0x1301bf;;;AU)(A;OICIIOID;SDGXGWGR;;;AU)
data\folder2
D:AI(A;ID;FA;;;BA)(A;OICIIOID;GA;;;BA)(A;ID;FA;;;SY)(A;OICIIOID;GA;;;SY)(A;OICIID;0x1200a9;;;BU)(A;ID;0x1301bf;;;AU)(A;OICIIOID;SDGXGWGR;;;AU)
Had I specified D:\Data in the command to restore the permissions, it would have failed looking for a
D:\Data\Data folder:
D:\>icacls d:\data /restore perms.txt
d:\data\data: The system cannot find the file specified.
Successfully processed 0 files; Failed processing 1 files
You might think specifying D:\ as the target in the restore command may somehow mess up the permissions on other folders at that level, but as you can see from the
ntfsperms.txt output file, it only has information about the
Data folder and subfolders, so that is all it will change.
And for Disk Hard and Soft Quota you can also backup the REG for recovery. For this you need the following REG backup.
