Full Restore Question

Did a point in time restore on Win2k Server EE MSSQL 2K EE sp3a
Database does a full back at 1am
Then from 4am on does a trans log backup
So had all file from 1am to about 5pm ( when the restore was attempted
)
I personally dont feel good about PITR but it was not my call.
Did the point in time recovery to 1206pm on that same day.
The restore ended up being right back at the time the restore was
started.
Any ideas?
I noticed doing the restore from Enterprise Manager when the checkbox
for point in time was clicked the list of backup files with checks by
them did not change.
Dont think they are supposed to.
How can I find out at what point in time the database actually did the
restore too?
EM has a but in the PITR dialog, as it natializes that datetime display and sends that string into
SQL Server, which in turn can be misinterpreted. Do the restore from QA and use a language neutral
way of expressing the datetime literals (STOPAT value), like 'YYYYMMDD hh:mm:ss'.

Question:
How buggy is just applying the full backup and then the transaction
logs that I need?
I have
1 full DB backup 1AM
- trans log at 4AM, 5, 6, 7, 8, 9, 10, 11,
12pm, etc
I wanted to go back to the 12PM trans log
so I can check all from 1AM to that 12pm trans log and I should be
good? Or does it natialize that also?
|||The dialog problem is datetime related. So if you don't do point in time restore, you don't specify
the date and time, and you will not see that problem. But why not just execute the RESTORE command
from Query Analyzer instead?

|||Well, since you don't do PITR, you will not get your most recent data. Also, as you have noticed,
there's a bug in EM, and such we will find from time to time. Learning writing and executing TSQL
makes us handle those situations quickly and solve the problem with minimal impact on your
production system. I think that Aaron has an article on EM vs. QA on www.aspfaq.com.

|||Thank You Tibor for your time and your professionalism.
I will read that article.
I will continue my walk away from the Oracle world !!!
