Difference between Full recovery, Bulk-logged, Simple recovery

what is the difference between Full recovery, Bulk-logged, Simple recoveryhi joe
full recovery means the entire db is recovered
bulk logged means part of the log is recovered
certain bulk operations are not recovered

you can apply the full log that contains bulk-logged operations).

Are you serious'
Why do you need to know?
Did you get a job as a SQL Server DBA without knowing this? Scary. Go to you
boss' office and hand in your resignation.
Is it a homework question for school? Are you so lazy and incompetent that
you cannot be arsed to research this by yourself?
You are a disgrace.

Difference between Full recovery, Bulk-logged, Simple recovery

Difference between Full recovery, Bulk-logged, Simple recoveryHi,
1. SIMPLE:-
Transaction log will be cleraed automatically after the checkpoint and hence
backup of transaction log is not possible. So we can
recover the database only until last full database backup
2. BULK LOGGED:-
Transaction log will be cleared only after the log backup but the below
operations are minimally logged.
SELECT INTO.
Bulk load operations (bcp and BULK INSERT).
CREATE INDEX (including indexed views).
Text and image operations
So POINT_IN_TIME recovery isnot possible in BULK LOGGED mode
3. FULL:-
Logs all the activites inside the database and with the help of
transactionlog backup you can recover the database point in time.
NOTE:-
For BULK LOGGED and FULL recovery model ensure that the log backup is
happening (enough room in hard disk), otherwise the
transaction log will grow and will eat the full harddisk space and will
create downtime.
Thanks

You must take a transaction log and then this option will be available.

diff. between simple and full recovery

Hi all,
do anyone know what is the different between simple and full recovery mode
in database properties.
thanksI suggest you search for the terms in Books Online. They are well described
there. Very short:
Full recovery mode allow you to perform transaction log backups. When you pe
rform transaction log
backup, the transaction log will be emptied.
In simple recovery mode, SQL Server will empty ("truncate) the transaction l
og for you, and
transaction log backup is not possible.

Diff between SQL server and SQL server Personal edition

Hi All,
I would like to install SQL server 2000 personal edition
on a workstation as a backup to my server. (disaster
recovery scenario) I run a backup to this machine already
every 30 minutes, all I would have to do is turn on SQL
services, restore the latest backup and I am back up and
running within a few minutes. The workstaion has a 2 GIG
processor and 256 Ram which I am planning on upgrading to
512.
Are there any downsides to running 6 clients hitting this
personal edition server? Is the PE the same as the server
edition? Does the personal edition have limitations that
the server edition does not?
Thanks,
GPThanks,
Yes I know Windows prof. has a conection limitation, but
are there any SQL limitations running on a workstation?
Thanks again for your input.
GP|||The technical differences between editions are listed in Books Online (see the architecture
section). I suggest you call MS to make sure you aren't violating the licensing agreement:

You can call 1-800-426-9400 (select option 4), Monday through Friday, 6:00

Just remember that a worstation edition of Windows (XP or 2000 Pro) both
have a limit of 10 concurrent client connections.

Diaster Recovery - Different Build Numbers

I have to test for a diaster recovery plan (in case the
building burned down) We do a full backup of the data
files on our SQL Server 2000 nightly. (Using Veritas with
SQL client) My job is to build a new server and restore
the databases. All is find until I try to restore the
master. Then I get the error that the build numbers are
different. I have applied all the service packs and
patches that I believe to be on the original box, but
cannot get the build numbers to match. Does MS list what
patches or updates are in which build numbers?
ThanksChris,
See if this helps
