I write to disk initially and then immediatly clone to LTO2 tape.  As soon
as the clone is done the tapes go offsite.  I have a script I wrote that
cleans off the Disk Devices once a saveset is 3 days old.

The disk device is much more forgiving for slow networks.  I have two file
servers that are across WAN links that peak at 50K.  You can imagine how bad
an LTO tape drive performs when being fed data at 50k/sec.

Going from the Disk to LTO2 tape lets me jam data onto the tape as fast as
possible especially since my Disk Devices are SAN attached.

Hey Shawn,

Do you use it more as a staging area, or do you keep the data online for
several days/weeks?

Thanks,

Joel

I'm Windows based, so may not apply. I have 2 500GB devices and one
200GB
device.  Works nicely.

Hey All,



Anyone using AFDs as their main targets for backups?  How large did you
create your devices.  It seems to me that the design of the AFD is
geared towards very large devices.  Anyone using a vxvm managed volume
cooked with vxfs as an AFD?  What size volumes did you go with?



TIA,



Joel
