Of course I'll try this before I go live, but I figured I'd ask
here first. I've read the docs, and the answer is unclear.
My current backup strategy is:
Take a full database backup occasionally (like, every two weeks).
Back up logs every five minutes.
This works, but restoring the database all the way through can
take a while, as I've sometimes spun through 800+ log restores.
I'd like to change to
Take a full database backup occasionally (like, every two weeks).
Take a differential backup every day.
Back up logs every five minutes.
So, I'd have this set of backups after day two
FULL
LOGS 1-100
DIFFERENTIAL
LOGS 101-200
When I go to restore, do I always have to do
FULL
DIFFERENTIAL
LOGS 101-200
or can I do
FULL
LOGS 1-100
LOGS 101-200?
I guess what I'm really asking is: is there any reason to keep
the "old" logs around (in this case 1-100), if I assume I always
have the latest differential?
I suppose I *might* need them to do a "point in time" restore,
i.e.
FULL
LOGS 1-53.
but assuming I never want to do that, can I discard the logs
that are earlier than my latest differential? 1 1768
Your understanding is correct - "full + all logs" or "full + diff +
logs since diff" are effectively the same thing, but as you say, using
differential backups can significantly reduce the time to restore.
Being able to do a point in time restore is the only thing you would
need the intermediate logs for, unless you want to keep them just in
case you lose or corrupt the differential backups.

My problem is that I need to set up a backup SQL Server 2000 machine
which can be used in case of a failure to my primary. All databases
(30 as of now) must be an up to the minute exact copy of production
and include most recent changes in data as well as any structure
changes (Tables, Views, SP's, Triggers, Users . . etc).

Hello,
Recently I've tried to restore backup made on SQL Server 6.5.
Unfortunately, the only version of SQL Server I currently possess is SQL
Server 2000. I have access only to that backup, because I've made it a
few years ago, and the main db file doesn't exist any more ;( I would be
grateful if you could help me a little ;)
