Sun S7xxx series backup - offsite replication
Over the next couple of years I'm looking at doing a couple of projects, firstly, this year I'll be looking to get a second disk based storage device to replicate our backups to - to be kept offsite (either in County DC or at another school to keep 100Mb throughput), then next year I'd like to look at getting a Unified Storage Device (ie Sun S7xxx series) to increase our usable space and increase access speeds to data across the network (and provide more VM space). This brings in a 2-fold issue:
We currently use BE2010R2 for our backup software, to make offsite more efficient we'd need to get the de-dupe addon (money money money) and then we'd need to look at options (NDMP?) for backing up the Unified Storage or NAS device efficiently.
I'd been looking at DPM for backups due to cost and the data transfer required for offsite replication (after initial) would be relatively small, and would be a constant stream (rather than a lets push 1.3TB on a saturday night), however this can't do CIFS or NDMP backup.
Looked at Ahsay due to it's offsite abilities, but not sure about it's Enterprise features (or CIFS backup ability). Other NDMP capable software seems to shift into enterprise class backup software (and enterprise cost)
So... how do you guys who have Sun devices do your backups, and what do those of you with offsite/online replication use (and if there's anyone who fits in both boats... info gratefully received).
