vvor dynamic serialization, the file is backed up, but the backup version of the filemight contain inconsistent data. Do not use shared dynamic or dynamicserialization for a file if it is very important that the backup version or archivecopy contain all changes.Does the backup copy group specify an adequate number of backup versions tokeep, along with an adequate length of time to keep them?Does the archive copy group specify an adequate length of time to keeparchived copies of files?Assigning a management class to filesA management class defines when your files are included in a backup, how longthey are kept on the server, and how many versions of the file the server shouldkeep. The server administrator selects a default management class. You can specifyyour own management class to override the default management class.To assign a management class other than the default to directories, use the dirmcoption in your options file.You can assign a management class for a file or file group by using an includestatement in your options file. You can also assign a management class by using aninclude statement in include-exclude file specified by the inclexcl option.Management class names are not case-sensitive.Using the command-line client, to associate all files in the costs directory with themanagement class budget, you would enter:include /home/proj2/costs/* budgetTo specify a management class named managall to use for all files to which youdo not explicitly assign a management class, enter the following:include /.../* managallThe example below demonstrates how to use a management class:exclude /.../*.snoinclude /home/winter/.../*.ice mcweeklyinclude /home/winter/december/*.ice mcdailyinclude /home/winter/january/*.ice mcmonthlyinclude /home/winter/february/white.snoProcessing follows these steps:1. The file white.sno in the february directory in the winter directory is backed upfollowing bottom-up processing rules. Because you did not specify amanagement class on this statement, the file is assigned to the defaultmanagement class.2. Any file with an extension of ice in the january directory is assigned to themanagement class, mcmonthly.3. Any file with an extension of ice in the december directory is assigned to themanagement class, mcdaily.4. Any other files with an extension of ice in any directory under winter areassigned to the management class, mcweekly.5. Any file with an extension of sno in any directory is excluded from backup.The exception to this rule is white.sno in the february directory in the winterdirectory.Chapter 9.
