Hello,

Yesterday I read replica(8), played with it a bit, and I have the
following question:

Say I have a directory A which I=E2=80=94from time to time=E2=80=94want to =
replicate
to directory B. With replica/updatedb I maintain two files, A.db and
A.log, describing the situation in the A directory.

If A.log has existed since the time replica/updatedb was run for the
first time, I may use this log as an input to replica/applylog and
create a replica of A in B.

However, I don't understand what one should do if this log was removed
or somehow shortened (so that it does not mention the files' addition
anymore).  Some such shortening is, I believe, reasonable, since after
say 10 years nobody is probably interested in all the files' changes.
But, if I understand, it is exclusively the log itself (i.e., not the
server database file A.db) that is used for synchronization by
replica...

Is there any more thorough explanation somewhere describing how replica wor=
ks?

Thank you for hints/explanation!
