Zip64 Plugin Reference
The Zip64 plugin is used for compressing to a zip file. The file format is not exactly the same as a zip file which is primarily a 32 bit archive with a 2 GB limitation. The zip64 archive format is a zip format using 64 bits, which should make it limitless for the near future. Z-zip is a great open source windows program that can read and write zip64 files, and many more types of compression formats as well. Of the standard plugins provided with SQL Server Compressed Backup such as gzip and bzip2, zip64 is good compromise between fast compression and small files. The level option affects the performance and compression ratio to a great degree, so it is worth trying different levels.
The example below compresses the data at level 3 and a filename of model.bak.
msbp.exe backup "db(database=model)" "zip64(level=3;filename=model.bak)" "local(path=c:\model.bak.zip)"
