We back up 30+TB each day.

We use EMC's timefinder, BCV's as a 3rd mirror, and mount them up locally to
a dedicated media server and then spin the data off to local tape drives.
This takes all load off the clients and runs the data over the SAN via the
media server to tape drives that spin between 20-30MB/sec.  We do also
perform a good number of network based backups but without a dedicated GigE
network there's no other way we'd be able to push this much data in this
short amount of time.  Understand this is also occurring across multiple EMC
frames with multiple media servers.

All,

 

I was curious if anyone here is backing up large amounts of data, such as
large databases and fileservers that are 3TB or bigger.

What is the best way to accomplish such backups?

 

Here is one 'idea' - please let me know if there are other, better ways:

 

If one can sustain 100 megabytes per second over a gigabit link writing to
multiple (5) LTO2 tape drives, each doing 20MB/s then it would still take
around 8 hours to backup this information, essentially you would need a
complete backup solution JUST for this 3TB array.

 

What are some good methods when backing up such large data sets?

 

Thanks!
