Re: [Bacula-devel] Selective restore when files are pruned [patch]


One suggestion might be to implement a backup object versioning scheme.
In most cases, the most active data in the system is the current version
of a backup object. What if we retained the current table structure for
the most recent version of each object, and moved any previous version
to the per client tables Kern has suggested. 

This would allow most of the common scripts to continue to work as is
(most of them are really concerned with the most current versions of the
data), and a view could be defined to provide a similar structure for
scripts working on older versions of files w/o impacting the current
performance for real-time backup processing. 

This would clearly hit the expiration processing and restore processing
(in that both would have to become aware of versioning) , and expiration
would have to be aware of the difference between whether this was the
last copy of an object or not, but I think that would be overall
valuable as well as solving this particular problem.
