Backing up Windows 7 with Backuppc

Categories: Blog.

Having recently upgraded to a new machine with Windows 7 the challenge was to get it to work with Backuppc. Read about how I got it to work again.

The computer shop installed Windows with an administrator of Owner. After setting up my applications all Monday the hard disk failed Tuesday morning. After another visit to the shop (also got a new monitor), and with new hard disk installed I could set up Windows how I wanted it.

The first user set up during installation was admin. This is to be used as the only administrator user and for backuppc.

Once set up I created the other users required. Next I shared c:users as a share called Users.

I set up Backuppc for the new machine. As it’s a bit different from the Windows XP machines I set up a custom configuration for it under the host’s home page (on backuppc) using link called Edit Config. Using this creates a file located and called /etc/backup/study.pl for my computer called Study.

Custom host configuration

Under the Xfer tab I changed the following:

SmbShareName Users The share name you want to back up.
SmbShareUserName admin User name you want to use for Backuppc
SmbSharePasswd [password] The user password. I found that short ones don’t get stored properly. Use one at least 8 characters long.
BackupFilesExclude *NTUSER.DAT
*Music*
GlennPicsMine*
You can use either BackupFilesOnly or BackupFilesExclude, but not both.First set up a key called Users. Then add the files you want excluded. The first * indicates any user.For a particular user insert their name.

After making your changes don’t neglect the Save button at the top!

Testing for errors

Once done I tried doing a backup. I was getting the directories OK but no files inside were backed up.

Checking the errors under Host home/Xfer Error Summary/Errors I found over 25,000 had NT_STATUS_CONNECTION_INVALID errors. Google was of little help for this one. Admin’s files were being backed up OK and I thought I would check how the Study computer looks from my Linux Ubuntu machine using the following dialogue.

glenn@pavlinux:~$ smbclient //STUDY/Users -U admin
Enter admin's password:
Domain=[STUDY] OS=[Windows 7 Home Premium 7601 Service Pack 1] Server=[Windows 7 Home Premiu               m 6.1]

Setting permissions; GUI, cacls or icacls?

All was looking OK and accessible. As admin’s files were OK it must be the permissions on the Windows machine were wrong. I only have the Home Premium version and the permissions GUI isn’t as good as Windows XP Professional.

I decided to use cacls but it looking at it’s help screen it has been superseded by icacls. Using icacls creates lots of permissions for your user that I have never heard about. Using the following I set the permissions to be more like cacls’ F for Full permissions:

C:Users>icacls glenn* /T /grant:r admin:F

The /grant:r removes the existing permissions and replaces them with F (Full) in this case.

It may require some fiddling. I got errors trying to set it initially. Try using the GUI to add permissions for admin. Then fine tune them with icacls. Next try doing a back up.

I found that some of my folders still aren’t being backed up and will need further investigating.

Windows goes too far with permissions I believe, they are too complex and can be hard to manage, and don’t get me started on Deny permissions!
