About this task
For example, the amount of data can increase quickly in
the following cases:
- Your client application uses functions that use text IDs, such
as DecideWithID or CreateText
- You configure the system to accumulate a large amount of feedback
before it is processed, or you configure the system to defer processing
of the feedback.
- You associate a knowledge base with learning data (SARC files).
Content Classification provides
two mechanisms for backing up your data:
- Back up the entire data server directory
- You can configure Content Classification to
periodically back up the contents of the data server directory to
a backup directory. If there is a problem with the computer on which
the data server resides or if the files become corrupted, you can
roll back to a previous version by using the backup files. You can
also store snapshots of knowledge bases and decision plans in the
backup directory. If the current knowledge base or decision plan is
corrupted, you can replace it with a backed up copy. For more information,
see Backing up the data server.
- Back up knowledge bases and decision plans when changes are made
- When you select the Back up automatically option
in the knowledge base or decision plan properties window in the Management Console, Content Classification automatically creates
backup copies of the knowledge base and decision plan when they are
changed. Each backup copy is assigned a unique version number. During
classification, all decision results and suggestions are associated
with the specific decision plan and knowledge base version that is
responsible for that decision. Storing previous versions of the decision
plan and knowledge base is useful if you need to reproduce results
from a previous version after the knowledge base or decision plan
was changed.
- The backup copies are created in the Classification_Home/dserverdir/VERSIONS directory
on the data server. The file name is the name of the knowledge base
or decision plan concatenated with the backup version number. Because
new versions are created whenever feedback is processed or you make
structural changes to the decision plan or knowledge base, many backup
copies can be created depending on how you configured the system.
- You can import a backup copy of a knowledge base or decision plan
into Classification Workbench, analyze
and edit if necessary, and then publish the knowledge base or decision
plan to the Content Classification server. Before you can import a
backup decision plan into Classification Workbench,
you must first convert it to DPN format by using the DpFromVersion88
utility. For more information, see the description of the Back
up automatically option in Decision plan properties.
Best Practice: Set up a procedure to store the backup copies in a secure
location for future reference and periodically delete the old data
from the data server.
In addition to backing up the data
that is stored on the data server, also back up the decision results.
For example, if you use the Classification Center to
classify and review your content, you can store a history of all classification
decisions by periodically backing up the Classification_Home/ECMTools/logs directory
on the Classification Center server.
Important: If you do not set up a backup policy for the
Classification Center events log, the history
of classification decisions is not saved.
Classification Center uses a recycling logs
process in which older versions of the
events.csv file
are deleted when the maximum number of log files is reached. The maximum
number of logs is 10 and the maximum file size is 10 MB. A best practice
is to back up the log files before the maximum number of log files
is reached and concatenate the date of the backup to each log file
name.
For the other Classification Center logs,
a new log file is created when the maximum log file size, which is
10 MB, is reached. To change these default settings, you can edit
the Classification_Home\ECMTools\ClassificationCenter\WebContent\WEB-INF\classes\log4j.properties file.
