Lsyncd Technical Session

So what is lsyncd?

Lsyncd is a tool used to keep a source directory in sync with other local or remote directories. It is a solution suited keeping directories in sync by batch processing changes over to the synced directories.

When would we use lsyncd?

So the generic use case is to keep a source directory in sync with one or more local and remote directories.

# THE SETUP

# Mail will be stored in non-retarded Maildirs because it's $currentyear.  This
# makes it easier for use with isync, which is what I care about so I can have
# an offline repo of mail.

# The mailbox names are: Inbox, Sent, Drafts, Archive, Junk, Trash
