説明

The wizard could in it's final step have a analyzer of the data and suggest better values for dblock-size and blockssize. For example if it notice most are small compressible files it would use current default. But if it find out most are non-compressible large files like images and specially videos it could suggest other more suitable defaults. Like a dblock size of 1Gb and blocksize of 100Mb for example. Without this the database could become too large when used with terabytes of data and the user wont understand why.

調査方針
Investigate the Duplicati codebase to locate the wizard logic and default values for dblock size and block size. Look at how file types are detected and how compression settings affect database size. The issue suggests analyzing data to recommend optimal values, so explore existing file analysis code or hooks. Review the 8 comments on the issue for any proposed approaches or concerns. Consider implementing a heuristic based on file size and compressibility, possibly using the existing backup data to infer file types.
