Subject Re: Backup and Restore of index files

: Those would be the individual files inside the lucene index, The "index" you
: want to backup is the entire 'solr/data/index' directory.  I imagine you want
: to think of that directory as an atomic unit, the whole directory at once
: describes your index, not the individual files in it.

Correct.  The filenames are segment identifiers that "increment" as the 
index is modified.  the directory *is* the index.

: Those names will change every time an 'optimize' command is run.

or anytime a commit is done if a segment merge happens.
