When Kaspersky Anti-Virus is active, the backup storage can be quickly filled.
The storage needs to be periodically cleaned of old and unnecessary backups.
This can be done using a special utility, backup-sweeper.sh, included into the
distributions package. The utility registered with the system as a cron task after
the installation can:
• distribute backup copies in special folders within the storage named as
year-month-date;
• check the storage size and notify the administrator when it becomes
critical;
• delete the oldest folders with backup copies.
For this utility, the following command line options are available:
–install – create the cron task for this utility under a default user account;
–uninstall – delete the cron task for this utility under a default user account;
–user – launch the process under user account other than kav;
–size – define the maximum size of the backup storage. The default size is
512 Mb;
–warn-only – ignore the specified maximum storage size; write in log file
about the current storage size;
–path – Change the location of the backup storage by specifying the full
path to the new location.
By default the backup storage size is 512 MB. Use –size option to set another
backup storage size when you register cron task. For example:
# ./backup-sweeper.sh –install –size 200MB
If the cron task is already created with another backup storage size settings,
delete it using –uninstall option and then install new cron task with the new
settings.

module updates
If you have registered cron task with the keepup2date.sh script, updates will be
performed every hour after Kaspersky Anti-Virus is installed on the server.
As an updating source, the application uses Kaspersky Lab update servers
defined by the UpdateServerUrl configuration parameter.
