We are putting together a new network infrastructure and my biggest problem has been deciding on a proper backup solution. We are currently using Veritas Backup-Exec -> REV Cartridges on our aging Domain Controller. Our backups have been failing left and right due to capacity issues and we have no off-site backup to speak of.
Our new infrastructure will be laid out as follows:
- Win2k8 DC, DNS, DHCP
- Win2k8 File Server, Print/Scan Server, WSUS
- VMWare ESXi w/ Secondary DC/DNS Guest, Application Server Guests, and Development Server Guests
We should have our 20Mb Fiber WAN installed before this new infrastructure is deployed. I like Vembu Storegrid because it allows for multiple backup destinations including automatic cloud based replication. We would also like to use RDX drives for monthly snapshots.
However, I don't know what the best solution is for local Disk->Disk backup. I've considered some type of iSCSI SAN such as a Drobo B800i or using some sort of NAS device. The advantage I see with using a NAS is that I could install the Vembu Backup Service directly on the NAS instead of the File Server. I would prefer to avoid a completely DIY NAS as I don't want any hardware failures to fall on my shoulders.
I would like to know what other's would do/have done with this scenario or if I'm going about this completely wrong.
Edit: I would only install Vembu on the NAS if it were running a full blown server OS (eg. WSS, Debian, RH)
