Re: On-Archie or OnBar ??

Mark brings up one of many major reasons why no 1st tier DBMS vendors
support table level backup/restore in their main backup/restore products.
I'm sure there are certain products out there claim to do just this but
unless it's an extremely simplistic scenario. i'm not sure DBAs want to
use them either. Think integrity, dependencies (index ...). What if the
table schema has been altered, i.e. column type changed, dropped, length
expanded... It's not as easy nor simple as one might think. You can always
do this with other provided utilities.
MS SQL server did have table level support with tons of caveats but dropped
it in 7.0
Oracle does have lower granularity PIT restore (tablespace) but the process
is nothing but simple. As Mark pointed out, integrity is the key here, Oracle
will need to re-sync everything to ensure that.
Without OnBAR, i don't know how you can manage a VLDB environment where the
typical size is getting close to 1 terabyte or larger and the backup window
is shrinking. It will take a while for onbar to mature.
