BSArc and BSA are compressed archive utilities, and associated file formats. They were developed by PhysTechSoft (PTS), a Russian software company better known for the PTS-DOS operating system (Wikipedia article). BSArc is also credited to Serg Babitchew. The relationship between BSArc and BSA is unclear.
BSA, at least, was apparently available for a number of different platforms. It lists DOS, Windows, OS/2, QNX, and Unix.

Identifiers
Confusingly, BSArc's default file extension is .bsa, and BSA's is .bsn.
Identification
A possible signature for BSArc's .bsa files is 0x00 0xAE at offset 1, followed by a byte with value 0x02, 0x03, or 0x07.
BSA's .bsn files probably begin with signature 0xFF 'B' 'S' 'G'. IDArc says this sequence may also start at offset 1 or 3.
IDArc also identifies a format it calls "BS2/BSArc", which starts with 0xD4 0x03 'S' 'B' ' ' 0x00.
