FSFS and BDB are Subversion file system implementations. Traditionally Berkeley DB (BDB) was the standard file system used by Subversion. It solves many serious concerns with BDB such as data corruption and added improvements such as smaller space requirements. Now the FSFS is the standard, the default setting, and recommended by Subversion developers.
How FSFS is Better
- Write access not required for read operations
- Little or no need for recovery
- Smaller repositories
- Platform-independent
- Can host on network file system
- No unmask issues
- Standard backup software
- Can split up repository across multiple spools
- More easily understood repository layout
- Faster handling of directories with many files
- (Fine point) Fast "svn log -v" over big revisions
- (Marginal) Can give insert-only access to revs subdir for commits
How FSFS is Worse
- More server work for head checkout
- Finalization delay
- Lower commit throughput
- Immature code
- Big directories full of revision files
- (Developers) More difficult to index
