I have a few questions about planning, and whether the requirements we hope for are possible.
At the primary site, we have around 20TB of data on an EqualLogic PS6100. This is connected to 2 VMware 5.5 Enterprise hosts. This is being backed up daily to an old 20TB MD3000i. This is where Veeam is currently installed.
At the DR site, we will have around 136TB on two EqualLogics, connected to 1 VMware 5.5 Enterprise host.
The sites will be connected via a 300mbit link
Looking at the data transferred locally, it’s around 100-140GB per day
Ideally, we would like to retain some backups at the primary site.
- replication to DR site (daily/every few hours/not sure yet) (EQL)
- long term backups, at DR site (EQL)
- last 30 days backup, at primary site (MD300i)
Should I move the Veeam server to the DR site, and then have a proxy at each site?
What effect will replication have on the primary site? I assume snapshots are taken, so the storage LUNS would need to be large enough to retain a day’s worth of changes (or whatever replication frequency is set)?
