Are you referring to differential backup or log backup?

Hi, not new....
Using the GUI to do backup, or configure the backup task in SSIS, specify to do 1) Full 2)Differential Backup.....


Short "how-to" - easy way...

1. Right Click your db in SSMS
2. Focus on "Tasks" -> "Backup"
3. on the general screen, look for: "Backup Type"
4. Select your backup type: Full or Differential etc....

and the rest of the criteria and file locations you need to modify as you need it...

Hope this helps....

Hi

This is not new to SQL2005.....

Easy way to do a Differential Backup..

1. Right click on you DB in SSMS
2. Focus on "Tasks" then -> "Backup"
3. In the Backup Type select 1) Full or 2)Differential.
4. Configure rest of the settings like file location etc....

You can also do this in SSIS using a Backup Database Task Step.

Hope this helps?

Hi

I know about Differential backup.

but the question asked by interviewer was "What is difference between differential and incremental backup in sql server". I have not heared about incremental backup and had no idea how to take this type of backup in sql sevrer because i have not seen this option in sql server yet.

Can anybody tell me where is this option in sql server ?

Please help me.

Thanks & Regards

A differential backup contains all the changes since the last full backup.
An incremental backup contains all the changes since the last incremental backup (or the full, if no incrementals have been taken yet).

Incremental backups are additive - you have to restore all of them to get back to where you started.
You can only restore one (complete set of) differentials (plus most recent log) to get back to where you started.

SQL Server does not support true incremental backups (I mean just pages which have changed since the last incremental).
The closest to it would be a series of log backups, I guess.

Differential backup is good up to the last full backup.

Incremental (transaction) backup is good up to the last incremental or full
backup.

There is nothing called incremental backup in sql server.

There are 3 types of backup
1)Full
2)Differential
c)Transaction Log

Syntax:Full
Backup database database_name to disk='Physical location' with stats=10

SyntaxBigGrinifferential
Backup database database_name to disk='Physical location' with stats=10 with differential

Syntax:Transaction log
Backup Log database_name to disk='physical location' with stats=10

The Ans will be same...

Differential backup takes place after the full backup, what are the changes happend, those changes
are stored in the DCM pages. Differntial backups will backed up those DCM pages.

next we will have to go for differntial backup then i will backup the data from full backup anwords...

thats way the differential backup is called it as Incremential backup...:-)
