Who has experiences with software distribution/syncronisation over WANs with NDMPcopy or SnapMirror?
We have a software pool at our master site, where we maintain our software (~ 500 GB) and then we distribute the changes to our client sites. Our actual rcp/ssh-based solution has several drawbacks:
- No automatic syncronisation
- Transfer of whole sw-packages only
- Only Unix-packages supported (no NT packages)
My idea is to do this job with NDMPcopy or SnapMirror, but I have a lot of questions: Can I export (ro) the mirrored volumes? (NDMP, SnapMirror)
SnapMirror, yes. The target volume of a SnapMirror operation is always read-only. If you make it read-write, another Level 0 dump is required.
It´s possible to tunnel NDMP/SnapMirror with ssh?
SnapMirror, no. NDMPcopy, maybe... I never tried.
Can I mirror more than one site with SnapMirror?
Yes, easily.
Cascaded distribution?
SnapMirror, no. NDMPcopy, maybe.
Is there a commercial product?
SnapMirror is a commercial product, contact your sales rep for more info.
Hope that helps.
