RE: Exchange on integrated x Series

Depends on the file system and the backup program.

Also depends on rather the real file was saved at the same time as the
symbolic link (ie. you saved /home/**)

It's been a while since I dealt with this, plus in reality you have to
deal with hard and soft ( symbolic ) links.

However (after a quick google), generally speaking I believe that for
symbolic links, the link is generally restored and if the originally
file is gone then you have a broken link.

For hard link, it seems to depend on the backup program to save one copy
or multiple copies of the data.  (Sounds like Exchange)

I'm not saying that Exchange doesn't use a valid solution to the
problem.  But given the number of duplicate emails floating around, and
the space consumed by them on tape.  I'm thinking that MS could have
made a better choice.

After all, you yourself said that brick level backups are being avoided
due to the space requirements.


Have a good weekend!
