IIS Backup Process


In addition to backing up web content files and associated databases, the IIS metabase (MetaBase.xml) and the metabase schema (MBSchema.dll) should be backed up. An automated backup of the IIS metabase and schema is made when changes are made or IIS is restarted. An administrator can use the IIS console or the iisback.vbs script file to do so. The script file can be modified. The script creates backup copies of IIS configurationthe metabase and schemawhich can be used locally or remotely and can also be used to restore IIS configuration. To use the script, follow these steps:


Iisback /backup /b IISbackup1 /e urtHv8c /s computer1

This command line will back up IIS on computer1 and give it the backup name IISbackup1. The password urtHv8c will be used to protect a generated session key used to encrypt the secure properties. You can read the backup copy and delete the file, but to restore the backup to IIS, the password is required. This can prevent an inadvertent or malicious restore of an older metabase and schema. The complete syntax for iisback is in the server help files. To restore the backup made previously, use this command:


Iisback /restore /b IISbackup1 /e urtHv8c /s computer1

To back up the metabase and schema from the console, follow these steps:


1.

Click Start, Administrative Tools, Internet Information Services.

2.

Right-click the name of the IIS server to back up, click All Tasks, and then click Backup/Restore Configuration.

3.

Click Create Backup and enter a name for the backup.

4.

To create a backup that can be securely moved to another server, click Encrypt Backup Using Password, and then enter and confirm a password, as shown in Figure 17-24 (only letters and numbers can be used). The secure data in the metabase is encrypted.

Figure 17-24. Enter a password to protect the backup.

5.

Click OK. The backup is made to the systemroot\system32\inetsrv\MetaBack folder.

6.

Click Close.


To restore the IIS metabase and schema, follow these steps:


1.

Click Start, Administrative Tools, Internet Information Services.

2.

Right-click the name of the IIS server to back up, click All Tasks, and then click Backup/Restore Configuration.

3.

Select the file name of the backup to restore and click the Restore button.

4.

Enter the password, if necessary, and click OK.

5.

Click OK to close the warning, which alerts you to the time restore may take.

6.

Click OK after receiving the success OK popup.


TIP: Metabase History on by Default

The Metabase history feature is on by default in IIS 6.0. This feature tracks changes to the metabase and metabase schema files and saves a copy of the file in the history folder. You can roll back the files from the history using the console Backup Restore Configuration option.
