Help ID-ing DOS backup format

Folks, I received a couple of DC6250 backup tapes this morning. While writing a program to unravel the backup format looks to be pretty simple, I'd like to know what created these beasts. They're from a Windoze box circa 1995. The "GENERATION" right at the start might be a hint. Here's a dump of the first few bytes of a tape, hex on the left, ASCII on the right: 000000 47 45 4E 45 52 41 54 49-4F 4E 20 EC E9 C6 F3 F4 GENERATION 8T?=( 000010 F4 E5 C2 20 20 70 6F 73-5F 62 61 63 6B 75 70 5F (s- pos_backup_ 000020 32 39 30 38 39 35 20 20-20 20 20 20 20 20 20 20 290895 000030 20 20 20 20 20 20 31 30-3A 32 30 3A 30 31 20 33 10:20:01 3 000040 30 2F 30 38 2F 31 39 39-35 20 4E 20 20 20 0A 31 0/08/1995 N ?1 000050 30 20 31 20 20 20 20 20-20 20 20 30 30 30 30 20 0 1 0000 000060 30 30 30 30 20 43 3A 5C-0A 32 37 20 30 30 30 30 0000 C:\?27 0000 000070 39 46 34 36 20 33 32 43-30 20 31 43 42 46 20 49 9F46 32C0 1CBF I 000080 4F 2E 53 59 53 0A 32 37-20 30 30 30 30 39 34 46 O.SYS?27 000094F 000090 41 20 33 32 43 30 20 31-43 42 46 20 4D 53 44 4F A 32C0 1CBF MSDO 0000A0 53 2E 53 59 53 0A 32 30-20 30 30 30 30 44 35 37 S.SYS?20 0000D57 Anyone got an idea? It's not MSBACKUP, nor SYTOS. Thanks, Chuck
