We have a very challenging system to back up: 1. We have 20 TB of data right now. 2. Each month we get another 3 TB of data, and about 5 TB of data changes each month. 3. We are currently a Windows-based shop and use DELL MD1000 systems.
We want to: - Fail over in real time to the most recent backup copy of the data. - Be able to restore previous versions of the data for the past 60 days.
NOTES: - Because of all the writing and re-writing to disk, file corruption is fairly common, so snapshots that don't duplicate data and not very useful. - Keep in mind that decompressing 2 TB of data in order to restore would result in days of downtime. Even just copying the data could take forever.
** What possible solutions do we have? **
