Hi to all,
We currently have 1 x NB 6.5.4 (Win2003) Master Server with a SCSI attached Dell TLD containing 6 x LTO3 tape drives. Additionally we have 1 further media server (Win2003) which we use for disk backups (occasionally as it is extremely slow!). We also have 1 x NOM (Win2003) server and 1 x NB PureDisk 6.5.1.2 (PDOS) server which has 2TB of local disk space.
We have noticed that since we introduced multiple copy backups and all 6 Tape devices are in use, the NB platform slows to a halt. We are going to try and spread the load around a bit more. Our thinking is that we buy a media server for each of the 3 LAN's that have servers that we backup (SQL DB and File/Folder backups mainly). Each of these new media servers would either have a lot of local disk storage or would use DAS hardware. We are keen to get more out of our PureDisk software and are considering beefing that up and making it a clustered environment to an offsite device.
Quite simply, I have been asked to provide a design document and I wanted to ask if anyone had any reccomendations on how they think we should invest? Our largest backups are around 2TB and these happen on a weekly basis. We also send tapes offsite on a weekly basis for the critical backups so we are not keen on disk-only solutions. We are happy to upgrade to NB7.0 too if this has any relevance with regards to our forthcoming hardware purchase.
Any advice greatly appreciated.....
Martin
