SQL Server Compressed Backup will back up SQL Server databases using either gzip, zip or bzip2 compression.
The new features are:
- Fixed the encoding problem by removing “\s”, “\p” and “\\” since they are commonly used in file paths and replacing them with “;;” to mean “;”. Looking at the command line options, it is only necessary to encode the semicolon, so “;;” is the only encoding the command line does.
- Added a feature I’ve personally wanted: progress updates and an estimated time until completion. It is more verbose at the beginning (every few seconds), then slows down. After an hour of backing up, updates are only once every 24 minutes.
- Worked on the BlockSize and BufferCount request. I’m not keen on implementing BlockSize. I’d like to hear someone explain how they take advantage of it. My understanding is that BlockSize is only for writing to devices (tapes and CD-ROMs — not files on a CD-ROM though), so it doesn’t seem appropriate for backing up to files. BufferCount and MaxTransferSize seem like reasonable options to request, so these are now available.
