Force a full backup
How does one force a full OS backup on a client that has been running awhile? [Avamar]
Thanks...

Moving aside or deleting the cache files will force the client to re-chunk all the files on a system. I'm sure you're already aware of this but removing the cache will be very bad for performance.
The caches are called f_cache.dat (for the "monolithic" file cache), f_cache2.dat (for the "paging" file cache) and p_cache.dat (for the hash cache). The caches are located in the "var" subdirectory of the Avamar client's install path. The default locations are /usr/local/avamar/var on Linux and c:\Program Files\avs\var on Windows.
There normally isn't a good reason to force the client to re-chunk everything unless there's some known issue with the integrity of the data but the properties of the file have not changed.

Specifying --nocache will prevent the client from using the caches as long as the flag is present but unless the backups referenced in the cache have all expired, the client will go right back to using the data in the cache as soon as you remove the flag.
Assuming you were to let all 16 backups referenced in the cache expire (meaning the cache is completely invalidated), you might as well have just moved it aside or deleted it at that point.
