Let's say I have database named db1 on SQL Server. I have daily backup, and I wanted to restore month old backup to new database, so I can recover just some info.
I created database db2, and tried to restore the db1 backup to new and empty db2 database.
I got message that backup I selected does not contain db2 backup and it started to restore db1 itself!!!
So now, for quite some time, next to db1 there is message (restoring...)
How can I stop restoring db, I didn't wanted to restore db1 at first place, and that's why I choose to restore backup to db2 destination.
Is there any chance I still have today's db, not this one month old?
I still can't open db1 to see what I have there, because it's not accessible.
Thanks.
Sorry but I am sure you are using GUI and you were not carful in that even. Please use query over GUI for max work.
Now your issue, I am not sure if you already fix but as no reply on web
Now you lost your database, its of no use. So find a latest backup and restore db1 (you can use point in time recovery if you have t-log backups)
Restore db2 with 30 days old backup by query , use move option in restore or create new empty database first and then restore same with replace option.

I'm setting up an Azure SQL DB for our Web App. We have enabled Point In Time Retention (PITR) and Long Term Retention (LTR). Our process is to keep backups for 1 year.
Periodically, we need to upgrade the DB by applying SQL scripts. Sometimes there is a problem with the upgrade scripts and the upgrade fails. We need to rollback the database to the previous version.
To rollback the DB I tried the restore feature. However, the restore feature seems to only create new DBs; therein lies the problem. Restoring to a new DB and removing the old one works great, but we lose all our backup history. It appears backups are tied to the DB (probably to the ResourceId).
So, how can I use Azure SQL DB and periodically restore a DB and still maintain all the back up history?
Unfortunately, restoring from a backup in Azure SQL Database always creates a new database. The secret here may be to rename the newly restored database with the name of the original database. You will even see that the restored database once renamed it then shows all the security recommendations, automatic tuning recommendations of the original database.
So delete existing database, restored the database, and rename it as the original database.
You can reference this document Recover an Azure SQL database using automated database backups , it gives the answer that all the recover are creating new database.
By default, SQL Database backups are stored in geo-replicated blob storage (RA-GRS). The following options are available for database recovery using automated database backups:
Create a new database on the same SQL Database server recovered to a specified point in time within the retention period.
Create a database on the same SQL Database server recovered to the
deletion time for a deleted database.
Create a new database on any SQL Database server in the same region
recovered to the point of the most recent backups.
Create a new database on any SQL Database server in any other region
recovered to the point of the most recent replicated backups.
If you configured backup long-term retention, you can also create a new database from any LTR backup on any SQL Database server.
improtant:
You cannot overwrite an existing database during restore.
"So, how can I use Azure SQL DB and periodically restore a DB and still maintain all the back up history?"
You can use Database replacement:
If the restored database is intended as a replacement for the original database, you should specify the original database's compute size and service tier. You can then rename the original database and give the restored database the original name using the ALTER DATABASE command in T-SQL.
Hope this helps.
Brief background info
We´re moving a database from Windows Server 2012 to 2016 in a critical production environment and are experiencing problems where the database on the new server gets set to Restricted user after the restore is done.
This is the order things are done:
2012 db is manually set to restricted user
Backup is made from 2012 db
2016 db is restored using backup in step 2
2016 db is unwillingly set to restricted user
The reason that we set the 2012 db in restricted user in the first place is to force logged in users to a stand-by environment while the 2016 db is being set-up.
The team that is doing this backup and restore claims that the database state is included in the backup as well and that that's the reason the new database get's set into restricted user as soon as the restore is done.
The new database being set to restricted user is not a huge problem since it's possible to manually change it back to multi user, but since this environment is of such critical nature, we don't want to risk having our users on the backup system any longer then necessary
So here's the actuall question:
When restoring a database from a backup, is the database state included in the backup and brought to the newly restored database? And if so, is it possible to exclude this?
Thanks in advance! :)
The RESTORE documentation states:
During a restore, most of the database options that are settable using
ALTER DATABASE are reset to the values in force at the time of the end
of backup.
So if the source database is in RESTRICTED_USER, the database will be set to that mode during the restore. You can, however, specify the WITH RESTRICTED_USER option during the restore to set the restored database to RESTRICTED_USER if the source database was backed up with a different option.
But there is no RESTORE option to specify WITH MULTI_USER so you'll need to execute ALTER DATABASE after the RESTORE to change the option.
I am not sure if I know what I'm doing: I am trying to backup "Integration Services Catalogs", seen in the picture below.
But all the instructions I get is to backup the SSISDB database. All I am familiar with is the catalog, that's where I go to "execute" my packages.. I know executing is just running some commands/script to run SPs within SSISDB database, but 1) if I was to make a backup of SSISDB, would that also give me a full backup of the catalog too?? How so? So restoring the DB would give me back my catalog ???
If the answer is yes, why do I need to BACKUP MASTER KEY Transact-SQL statement as part of the backup procedure (according to my studies), wouldnt this just be a simple DB backup???
Thank you very much in advance
Everything in the catalog is stored in that database, so yes, backing up that database backs up the entire catalog. Also there is encryption happening in the catalog, so having a backup of the master key makes sense. But notice that this article states that this is not required.

I was given a .bak from a MS SQL database and am needing to import the database onto a different workstation. I created a blank database in SQL Management Studio and attempted to restore from the .bak. The restore lists as successful, but only system tables appear in the restored database.
Am I missing a step?
Per the conversation in the comments, you had a backup of msdb rather than the database you wanted. You can do a restore with headeronly from disk = 'name of file here' to see what database is contained in the backup.
How can I restore just one table from a database backup in SQL Server?
I don't believe this is possible.
A better option would be to Generate Scripts from the first original database, and choose 1 table, and Script Data. Then execute this script on your database (where you wish to restore just 1 table).
If you don't have access to the original database, then restore the backup to a new database, create the Generate Scripts.. script from there, and then remove the new database.
