Solution Title: Failed to get status of file XXX during Incremental backup of Windows machines
Affected NV Version: 7.x
OS Version: All
Plugin version: N/A
Application version: N/A
Description:
On a Windows NT/2000 machine with NTFS partitions, it is possible to set permissions on a directory/file such that only the user has access (no access to Administrator).
Symptoms:
In this case NetVault will be able to backup the data in a Full backup, but incrementals/differentials will fail to back them up with the message 'Failed to get status of file ...'. The extended log message will show an 'Access Denied' message from the Filesystem.
The reason this occurs is for an incremental/differential backup, NetVault scans the filesystem first to build a list of changed files which need backing up. This is done by getting the status of each file (stat). In this case, we do not have permission to read the file attributes, and thus the message 'Failed to get status of file ...'.
By default the NetVault Processes run as user 'SYSTEM'. A workaround to this problem is as follows:
For Windows 2000/XP:
Using the NTFS 5.0 extended attributes, give the SYSTEM account the extended attribute 'Read Attributes':
1. In Windows Explorer right-click the folder containing the target data and select Properties. Go to the Security tab.
2. Click Advanced, then Add.
3. Select the SYSTEM user.
4. SYSTEM only requires 'Read Attributes' to be allowed.
5. OK this and allow the properties to propagate down through the filesystem tree beneath it.
