The Arcserve Backup Tape Engine identifies all the backup devices that are connected to your system. The default configuration log options can be changed; for example, when you want to troubleshoot a hardware or Tape Engine-specific problem.
Arcserve Backup provides the following Tape Engine options.
Message Log Options
None--No information is logged. Tape Engine logging is halted and the Tape Log tab does not appear in the Job Status Manager.
Summary--(default) Logs critical messages and reduces the size of the tape log by excluding unnecessary information. For this option, the Tape Log tab does not appear in the Job Status Manager. The TAPE.LOG file, by default, is generated and stored in the Arcserve Backup\Log folder. If the log path needs to be changed, you can do so by creating an alternate log path entry in the registry file. For more information about creating an alternate log path entry, see the Setting an Alternate Log Path Entry topic.
Detail--This option logs all commands sent to the attached backup devices by Arcserve Backup. Reads/Writes and Test Unit Ready commands are excluded. Tape Engine specific information, which may be used by Arcserve to help troubleshoot backup and restore issues, is also logged. The TAPE.LOG file, by default, is generated and stored in the Arcserve Backup\Log folder. If the log path needs to be changed, you can do so by creating an alternate log path entry in the registry file.
For more information about creating an alternate log path entry, see the Setting an Alternate Log Path Entry topic. The TAPE.LOG file for this option can be viewed in the Job Status Manager by accessing the Tape Log tab.
Detail with Read/Writes--Logs all commands sent to attached backup devices by Arcserve Backup. Unlike the "Detail" option, this option includes Reads/Writes and Test Unit Ready commands. Tape Engine specific information, which may be used by Arcserve to help troubleshoot backup and restore issues, is also logged. The TAPE.LOG file, by default, is generated and stored in the Arcserve Backup\Log folder. If the log path needs to be changed, you can do so by creating an alternate log path entry in the registry file.
For more information about creating an alternate log path entry, see the Setting an Alternate Log Path Entry topic. The TAPE.LOG file for this option can be viewed in the Job Status Manager by accessing the Tape Log tab.
Note: You may incur potentially large log file size due to the Read/Write capability. Read/Write logging may impede performance on the machine.
Both Screen and File--The messages are recorded in the Tape Engine Log as well as to a DOS box (the Tape Engine Message window).
Screen Only--The messages are sent to the Tape Engine Message window only.
File Only--(default) The messages are recorded in the Tape Engine Log only. You can view the Tape Engine Log in the Job Status Manager.
Important! If you select either option, Both Screen and File or Screen Only, you must configure the Arcserve Backup Tape Engine service such that it can interact with your desktop and display the contents of the tape log in a DOS window.
To enable interaction with the desktop:
The Arcserve Backup Tape Engine Properties (Local Computer) dialog opens.
Limit Log Size Options
The Limit Log Size By value divided by the Log File Count value represents the maximum size of all chunked log files. For example, if you specify a Limit Log Size By value of 100 MB and a Log File Count of 10, Arcserve Backup chunks TAPE.LOG when it reaches 10 MB (100/10=10).
The default value for the Limit Log Size By option is 100 MB, and the range is between 1 and 2000 MB.
To disable Circular Logging, clear the Limit Log Size By check box.
The default value for the Prune Logs Older Than option is 100 days, and the range is between 1 and 365 days.
Log File Count--Specifies the number of chunked log files Arcserve Backup retains.
The default value for the Log File Count option is 10, and the range is between 3 and 32.
Note: You can modify this setting only if the Limit Log File Size By option is specified.
Single Log File Size--This option works in conjunction with the Prune Logs Older Than option. When you specify the Single Log File Size and Prune Logs Older Than options, Arcserve Backup switches to Circular Logging mechanisms when the TAPE.LOG reaches its maximum size, and deletes chunked log files when their age is greater than the value specified under the Prune Logs Older Than option.
The default value for the Single Log File Size option is 10000 KB, and the range is between 1 and 100000 KB.
Note: You can modify this setting only if the Prune Logs Older Than option is specified.
General Options
Note: This option is only available on Windows computers.
