Write cache properties

The write cache describes a hard drive in the Storage Manager server on which volumes have been collected for burning.

Open the properties dialog using the context menu of the write cache:

Figure: Cache Properties/Write Cache dialog

Write Cache tab

Name

In the Name field, you can see the free memory.

Paths

Paths option group:
In the Local cache path field, you enter the path for storing the archived data on the hard disk. The directory name must already have been created.

In the Image file field, you enter the local path and file name.
The entered (sub-)directories must already have been created.

You cannot use UNC paths for the image file and write cache! This can lead to problems with data transfer and data access, depending on the individual network performance.

Automatically move files to the read cache

If this field is checked, the Move automatically option field opens. There, you can set how often the write cache is to be checked for data to be moved and the minimum number of MB which have to be free in the read cache. Another check gives you the option to log files in the current SM log file as well. You specify the SM log path under Tools/Log settings on the "File" tab.

Basic settings

Number of copies

In this field, you can see the number of copies of a volume to be created when burning to CD/DVD. The minimum entry here is 2.

Reserved memory (MB)

In this field, you enter the minimum size of the hard disk memory to be reserved on the hard disk of the local computer.
Example:
If you set 9,000 MB for a RAID system with a 16 MB capacity in the Reserved memory field, the Storage Manager works with 7 GB for the cache from that point on.
