What _seriously_ slows down backups is disk seeking (both on the client array and on the spool disks), and tape drive will slow to a crawl if not fed at near-full speed. If you're backing up to LTO of any type, the only way to get reasonable performance is to backup to a high performance SSD spool (or SSD stripe) and then despool from that to the tape. A decently fast SSD spool area can handle simultaneous spool/depool operations - but do NOT try this with low end consumer SSDs, the write latencies will kill performance (most consumer SSD random write performance is "so-so" at best.). ------------------------------------------------------------------------------ Infragistics Professional Build stunning WinForms apps today!
