HI James,

Can you suggest any upper limits you might recommend for Qrecall , such as archive size, or number of files in an archive ?

thanks !

A QRecall archive is currently limited to 6 terabytes. Since QRecall's data de-duplication usually runs around 60%-80%, this would represent somewhere between 15 and 30 TB of captured file data. (That's a lot.)

This limit is for a variety of reasons, but mostly because extensive testing shows that archives greater than this size are only marginally usable. The amount of effort required to perform data de-duplication increases exponentially as the size of the archive grows. At the 5 TB size, it gets pretty sluggish. Note that there are new features in QRecall 2.0 that make capturing to large archives more manageable, but I've yet to have a customer tell me that they need a bigger archive. But if it's any comfort, there's no technical reason this can't be raised to 10 TB, and with some software work extended even beyond that.

There's no limit (per se) to the number of files, but there is a limit to the number of records in the archive database. Since each unique file requires at least two records (one record for the file metadata and one for its content data), there's a theoretical limit of about 200,000,000 unique files, or 400,000,000 duplicate files, in a single archive. But these would have to be atypically small files; you are much more likely to bump against the 6 TB archive limit first.
