regex + sbackup

[dave s]

OK this may be dumb but ...

I have installed sbackup, it backs us up some directories but I do not want it 
to backup any sub directories called just 'data'

I used the regex option and entered

^data$

It still backs up data directories ... there goes 1GB ... If I change the 
regex to just plain

data

it works fine but it also excludes 'process_data' python directories.

Either I have my regex wrong (very possible) or sbackup is not working the way 
it should. 

Can anone shed any light on this problem before I commit a bug report ?

Cheers

Dave
