Hi Friends,


I am currently using Samba on Centos 4.4 as a domain member of AD 2003
with each user having a quota of 2GB(no of users is around 2,000). Now
the management wants to increase the quota to 10GB with this there
will be more than 20TB of data to be backup weekly which will take
lots of hours. Currently Veritas backup software is used to backup
data on tapes.

There is a concept of snapshots of Samba with LVM where snapshots of
samba are taken at the given interval but so far haven't found any
good article or how-to on that and also what is the experience of
users using this technology and also what other technologies are being
to handle TBs of data.


Kindly let me know if you need any further inputs


Thanks & Regards

 Ankush
