• rename – rename the attachment using the following rules: if the filtered
file has any extension, then it will be replaced with the vir extension, if the

(FilteredNameAction parameter).
7.8. Configuring backup options
Backing up messages is an advanced feature of Kaspersky Anti-Virus. Before
applying any action to original messages, you can back them up in a special
storage. This is a data safety precaution because you can always restore the
original information if needed.
The following backup policies are available:
• message – create only a backup copy of the original message.
• info – create a copy of the original message and an information file
(default policy).
• none – do not back up messages.
To define backup options, specify the action as the value of the BackupPolicy
parameter of the [group.backup] section.
Messages with the following statuses can be backed up:
• cured – messages to be disinfected;
• deleted – messages containing objects to be deleted during the anti-virus
processing;
• dropped – messages that will be deleted without sending to the recipient;
• rejected – rejected messages;
• warning – messages which content should be replaced with a warning;
• renamed – messages containing objects that will be filtered (by MIME
type) or renamed;
• all – all the above types of messages.
To define the messages that will be backed up, specify the corresponding value
for the BackupOption parameter, for example:
BackupOption=deleted
BackupOption=dropped
All backup copies are stored in the directory defined by the BackupDir
parameter, and, as was noted above, can also have an additional information
