SIS and Filesystem level backups (was just Re: Filesystem level backups?)

[DurgaPrasad - DatasoftComnet]

Hi all,
I am deeply interested in this topic considering that SAN level snapshots are not possible.
How do we effectively backup and restore SIS enable mdboxes?

Hi Ivan,

Mind if I ask for details?

(and maybe Aki or Timo):

I was considering implementing SIS on a new server I'm planning (won't be for a few months now probably). I had decided against it a long time ago because it was new, and there were drawbacks (backups not being properly accounted for being one of the big ones). I was hoping it had matured a lot since then and the drawbacks at the time were mostly history. Maybe that is not the case?

If not, are there open bugs dealing with the issues, and plan for addressing them? Or is SIs just probably not ever going to be ready for prime time?
