WM Configuration

When this happens, the archiver tracks the combined time and size of all open and closed files, compares the total to the configured Archive Duration and Archive Maximum File Size, and continues recording until the limits are reached. For example, if you configure the archiver for a two-hour duration, and there is a disruption that forces it to close one file and open another, the time in file1 plus the time in file2 will equal two hours regardless of how long the disruption lasted. When the archiver is configured with a duration and a file size set to 0 (Maximum), the archiver limits are 4 GB or 12 hours, whichever comes first, no matter how many disruptions occur and how many files are created.

Note Although a 60 GB hard drive can store thousands of files, it is important to understand that there are certain practices that can adversely affect overall encoder performance. For example, a large number of small files can consume excessive memory and therefore limit other encoder functionality. For example, if the hard drive is nearly full of small files and you have 20 progressive downloads in progress, the total number of push and pull clients (approximately 200) that can be effectively supported via HTTP may be significantly reduced. For best results, purge unnecessary files from your hard drive, avoid creating large numbers of small video files, and periodically run the Check Disk and Format utilities (see Diagnostics: Hard Drive on page 117) for more information.
