Linux Cure for Exchange Storage Bloat
,----[ Quote ]
| Users spend precious work hours copying e-mails to desktop PST files – which
| may be backed up rarely or never – or other secondary e-mail storage systems,
| copying them to their hard drives, or just deleting these important business
| records. If an employee needs to reference an old e-mail, he has to remember
| what it was called and where he filed it, then reload the PST file and search
| for the message. The productivity hit can be huge, and there is no guarantee
| the employee will actually find the critical information he is looking for.

| Modern Linux filing systems such as XFS and Ext3 leverage these optimizations
| and support features such as journaling (to ensure hierarchy integrity
| following a power cut), clustering and replication (DRBD), and snapshots (via
| LVM). With modern e-mail server architecture, IT can complete backup
| operations without requiring a freeze or a database snapshot.

Why so many filesystems for Linux? What's the difference?

| * EXT3
|
| * Most popular Linux file system, limited scalability in size and
| number of files
| * Journaled
| * POSIX extended access control
|
| EXT3
| file system is a journaled file system that has the greatest use in
| Linux today. It is the "Linux" File system. It is quite robust and
| quick, although it does not scale well to large volumes nor a great
| number of files. Recently a scalability feature was added called
| htrees, which significantly improved EXT3's scalability.

|
| * FAT32
|
| * Most limited file system, but most ubiquitous
| * Not Journaled
| * No access controls
|
| FAT32
| is the crudest of the file systems listed. Its popularity is with its
| widespread use and popularity in the Windows desktop world and that it
| has made its way into being the file system in flash RAM devices
| (digital cameras, USB memory sticks, etc.). It has no built in security
| access control, so is small and works well in these portable and
| embedded applications. It scales the least of the file systems listed.
| Most systems have FAT32 compatibility support due to its ubiquity.

Microsoft shipped OneCare unfinished?
,----[ Quote ]
| Since shipping in May, OneCare has failed industry tests and exposed
| users to attack because of a security flaw in the antivirus engine.
| The application also incorrectly flagged Gmail as a virus and in some
| cases quarantined or even deleted complete in-boxes when a single
| e-mail was laden with a virus.

| Asked about these problems, Arno Edelmann, Microsoft's European business
| security product manager, told ZDNet UK on Thursday that the code itself
| has pieces missing.
| "Usually Microsoft doesn't develop products, we buy products. It's not a bad
| product, but bits and pieces are missing," said Edelmann.
