Hello Pinal,
I found your instructions for scripting a backup. When snapshots are used, the dabase will not detach. If you remove a snapshot, it cannot be re-attached. Also, when doing a backup (.BAK), snapshots are not captured. This vulnerability is having us rethink the use of snapshots. They work great in the reports we use them for, but would leave us in a bad spot if we ever had to do a recovery from .BAK.

I’m creating snapshot DB from a mirrored DB, but in some cases it takes more than 15 minutes to create the snapshot. any idea why this could happen ?

This post helps to understand the basics of database snapshots in a clear view. Really helpful.

[...] Introduction to Snapshot Database – Restore From Snapshot A Database Snapshot is a read-only, static view of a database (the source database). Multiple snapshots can exist on a source database and can always reside on the same server instance as the database. Each database snapshot is consistent, in terms of transactions, with the source database as of the moment of the snapshot’s creation. A snapshot persists until it is explicitly dropped by the database owner. [...]

I love this! We have a test server where I test application changes. This would be perfect for reseting the database back to the original values to rerun a test in seconds! Plan to try that.

use your database logical file name(Name of your .mdf file)

Right click on database->properties->files.

alternatively you can use
use ‘yourdb’
select name from sys.database_files.

Thanks,
Deepraj

Hi Pinal

Am new to this concept and i have doubt regarding this post.. While creating the snapshot , the filename is given a path (FileName=’c:\SSDB.ss1′).. What does this path stand for?? Is it the path ofthe DB that you created(RegularDB)??

can we use database snapshots for reporting purposes.
Because on live productions databases querying tables causes sometimes locks.
Is it a good idea using for reporting?
Thanks

It means that RegularDB is currently being used by some other users. You need to disconnect all users before trying the code

Hi ,
I tried that snapshot.It shows the following error

Msg 5070, Level 16, State 2, Line 1
Database state cannot be changed while other users are using the database ‘RegularDB’
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.

What is the solution?

When I do this in 2008 R2, I see the size of the snapshot the same as Original DB Size. What exactly am I doing wrong?

Thanks

In First Post
>> When any data page is modified in the source database, that data page is copied to Snapshot database, making the sparse file size increases.

>> In other words, the changes that happen in the source database are reflected in the Snapshot database.

Which data? modified or original data page get copied to snapshot?
My understanding is original page copied to snapshot.

Dave,
The online book says:
When a page getting updated on the source database is pushed to a snapshot, if the snapshot runs out of disk space or encounters some other error, the snapshot becomes suspect and must be deleted.

Gr8 article. One thing I ran into when created a snapshot during upgrade was performance impact. I thing this sparse file becomes so busy when too much is going on with db that DB went extremly slow. Since than I have stopped using it during upgrades for backup.

Snapshot are read only. To create a near time reporting database look into log shipping. Your target database can be read only and in continuous recovery, so the latest transactions are applied.
