I have searched high and low but couldnt find anything.
Can you please help me with a restore database script from TSM; but via SQL Server agent job?

I manage to get it running for backups; but restores not working at all.

Any idea/advice?

Regards

Everywhere I turn, I see different examples of how often to do fulls, diffs, logs, etc.
What’s the practice of determining how often to do them? With the power of modern servers, and the cheapness of disks, the cost is low compared to the benefit of having a recent backup. If your databases are not huge, why not just do an hourly full? That would make a restore super-simple.

I like differential backup as this way, I do not have to do laborious task to restore each log backup since the last backup. If any way I can get the database up, I will do it.

Kind Regards,
Pinal

I am a regular reader of your articles and I really admire the amount of knowledge you have and dispense.

I do however agree with the guy who called you up as you mentioned that he said that “if he does not restore all the differential database backups and only restores log backups it just works fine.”

What you have explained in your article is a faster step to achieving the latest restore point, but it doesn’t conflict with his statement in any way.

The end result of the 2 procedures is the same, i.e:

His Way
1) Restore Full Backup >> Restore All Log Backups in proper sequence

Your Way (or better way)
2) Restore Full Backup >> Restore Last Diff. Backup >> Restore All Log Backups taken after the last Diff. backup

According to him this is an unnecessary step.

So why is it that what he said was, incorrect ?

It is an unncecessary step, only your way is presumably faster !

Please correct me if I have misunderstood.

Is there anything that can be achieved with a Diff. backup that cannot be achieved with Log backups ?

I have setup my Microsoft SQL Server database backup on the following schedule:
– Full Backup run on Sunday.
-Different backup run on Everyday at 11:00 PM
– Transaction log backup run on Every 4 hours everyday.

The backup was stored in second server’s hard drive (2 TB).

Questions:
1.Should I overwrite the backup file or append?
2.What is the best practice to implement Microsoft SQL Server database backup?
3.In the production servers, how is the DBA implement and setup the database backup?
Many thanks,
Edwin

this is good illustration for some of the SQL DBA professionals who have misunderstandings about differnetial backups.
Nice article Pinal way to go.

This is For Rick Martinez,
AM i right to understand that you guys have configured log shipping,If yes then there’s no need to ship the differential on the Secondary database .it will automatically apply the logs on the Secondary warm StandBy database.

I guess you allready have cleard this issue you have, but just for others to read about it here´s an explanation.

You had a broken backup chain, explanation:

Let´s say you are using some 3´rd party tool like IBM TSM or Backup exec to do nightly backups, and you also do manual backups within your SQL server, the TSm one starts a full backup @ 22:00 and the SQL internal starts a Full backup @ 23:00
The problem is that the Full backup made by TSM/BE will be the 1rst full backup for TSM/BE, ´but since you have a Internal SQL backup dump this will render the next Diff backup done by TSM/BE unusuable since the diff between the First Full and next Diff will be the Diff between the Last full (SQL internal) and the Diff backup running in TSM/BE..

Which makes the last Full backup in TSM/BE totally unsuable.. Did anyone understand me?

Anyway here´s a blog entry that explains it much better..

Thanks for the article. I am new to SQL Server and am trying to do a Restore of the database.
I have 1. Full Backup
2. Diff Backup 1,2,3,4
3. Transactional Backup 1,2,3,4,5

I could restore from the full backup.
And then (as per your article) tried to restore from
the latest diff backup (diff backup 4)

It errors out saying
This differential backup cannot be restored because the database has not been restored to the correct earlier state.

SQL Server version is 2005. And the first diff backup is the larger than subsequent diff backups.

Am I missing something?

Please comment.

my live (production) database (very few people use it) of size 5 GB (has got 7 years data) and we scheduled each night 1 differential backup and weekly 1 full backup. “No other backups are scheduled (as per my DBA’s decision)” As we know, hardly this system will have 100-200 inserts/updates/deletes per day (not more than that) but if I see size of differentials backed up database size is 1GB per day. Is there a way I can reduce as my boss asking why is this so huge in size when very few operations carried out daily?? As i am a developer I have very little knowledge on dba concepts like backups/restores. Please advise asap on this.

I reported same at microsoft site as well but changing recovery model to simple did nt help me :(

Excellent article, very informative and persuasive.

I’m a little confused with Transaction Logs.

Are they incremental in the sense that Log Backup2_2 contains only the data modifications after Log Backup2_1?

Thank you.

We then restore the transaction log on the secondary database. Are we doing this wrong are we suppose to restore differential backups on the secondary database?

Our database is 250GB, we do a full backup on Wednesday, differential backup once a day (Sun, Mon, Tues, Thurs, Fri, Sat), and transaction logs every 30 minutes.
