Global Options Advanced Options The Advanced options determine how BrightStor ARCserve Backup handles the file system extensions during a backup. Windows System Options Note: These options are only supported on the Windows 2000, XP, and 2003 operating systems. The options available are: ■ Traverse Directory Junctions and Volume Mount Points-Selecting this option causes the backup job to traverse the volume or the directory being specified to and take a backup of it. At the time of restore of this session, you can restore files and directories contained in the referred to volume or directory. When this option is not selected, the backup job does not back up the volume or the directory being referred to by the volume mount point or the directory junction respectively. Therefore, at the time of restore, you cannot restore a file or directory contained in the referred to volume or directory. - Backup Mount Points as Part of the volume that they are mounted on-If you select this, the volumes referred to by the Volume Mount Points will be backed up as part of the same session as the Volume Mount Points. When this option is not selected, the volumes referred to by the Volume Mount Points are backed up as separate sessions Note: This option is available only when the previous option, Traverse Directory Junctions and Volume Mount Points, is selected. ■ Preserve File Hard Links-If you enable this, BrightStor ARCserve Backup preserves hard links during a restore. Multiplexing Options The following options regulate how BrightStor ARCserve Backup handles multiplexing. ■ Chunk Size-Sets the performance of restore operations and memory usage. The chunk size value determines the amount of contiguous data written for one session before data from another session is multiplexed. The higher the value, the faster the restore on some drives, but at the cost of memory size during backup. For most drives, the default value of 1 MB is recommended. ■ Maximum Number of Streams-Sets the maximum number of streams that can write to a tape at the same time. The default number of streams is 4 and the supported range is between 2 and 32. 3-12 Administrator Guide
