Scanning for viruses and other threats
Description
Symantec AntiVirus copies a file from secondary
storage to the local hard drive as a temp file for
scanning, but the HSM application leaves the original
file on the secondary storage.
This method is slow and not supported by all HSM
vendors. Because a file is copied from secondary storage
to a disk for scanning, resource demand is high.
Processor and network performance may further
degrade as infected content is detected when a repair or
deletion is returned to secondary storage.
To reduce some of the resource demand issues with the
Scan all files without forcing demigration option, this
option lets you specify that only files that have been
migrated recently and may still reside on faster
secondary storage are scanned. It may be appropriate to
scan files if they still reside on the faster secondary disk,
and skip demigration and scanning if the files reside on
the slow, long-term storage.
For example, files may first be migrated to a remote disk
after 30 days of no access. After 60 days of no access, the
file is migrated to CD-ROM or remote SAN storage. In
many cases, this method may still be slow because
accessing files without forcing demigration is a
relatively slow operation.
You can allow scanning of files that, for security
reasons, are normally not readable except by a specific
user.
