I think the "I just wanna know" gives it away.

Are you a backup admin? Do you have any server eperience? Do you know what these components are?

The above comments are not to be construed as an official stance of the company I work for; hell half the time they are not even an official stance for me.

In general, backup data travels via LAN from clients to media servers, and media servers store recieved data to destination storage like tapes, disks, or OpenStorage.

Tape libraries or VTLs are usually connected through SAN or directly attached through FC, SAS, Parallel SCSI or so. So, yes, in general, backup data does not travel through LAN when it goes from media servers to destination storages. If using OpenStorage or NAS disks, backup data travels through LAN.

When you configured FT(Fibre Transport), backup data travels SAN when it goes from clients(SAN clients) to media servers(FT media servers).

OK Thanks yasuhisa.

.So in case of SAN client and SAN media servers,Only Data travels from SAN only ?

SAN media server is limited version of media server that can store its own data only, and is not same with FT media server.

Do you mean "SAN client and FT media server"? If so, yes.


Ooops, someone vote down my previous post!!

As mentioned above, SAN media sever is limited edition of media server, and this can its own data to destination storage. Client host and media server host is same in this case, so data does not travel through LAN when backup data goes from client to media server.
