[ARSCLIST] TY vs Mitsui

Bill Prentice, you said,

In this scenario, what will you rely on for backup?  Do I recall reading that you will have mirrored servers at separate geographic locations?  Not being able to afford that, we are moving toward enterprise server based storage for .wav files with backups on the discs in question located elsewhere.  In addition, there will be backups on SDLT.  That provides two magnetic storage options (HDDs and SDLT) and one optical.

Well put.

Thank you all for the thorough treatment of this subject!
