SQL Azure Daily Automatic and Keep Unlimited Time
I am trying to do the azure tutorial: https://msdn.microsoft.com/en-us/library/f6899710-634e-425a-969d-8db1267e9471
But the STORAGE ACCOUNT dont show any option, and I already had a storage account.
Databases are now automatically backed up and you don't need to set this up, this is what I found with playing with it today:
Did you know we already backup your databases? You can restore
databases from automatic backups using the Point-In-Time Restore and
Geo-Restore capabilities. Learn more.
But if you need to maintain your own copies for longer periods of time: In manage.windowsazure.com, navigating to the DB and then "Configure" you will find this option.

I am trying to move my DB to Azure Managed Instance.
I would like to know what should I do about this.
I have the options of DB migration and DB restore to Azure managed instance.
Please let me know the difference between these 2 methods.
Normally you first do a full Backup and then migrate the Database.
If something go wrong then you Restore the Database.
But I don't know exactly how Azure M.I. works..
For database restore option; you can take a backup of your database and then you can restore that backup on the cloud if your application(s) or service(s) handle a moderate downtime or maybe you does not care about downtime. After the restoration you just need to redirect your database connections of your application(s) or service(s).
For the database migration; it is a little bit more complex. Generally, this option has been using for database systems which we do not want to take downtime on it. Also, for this option you will always need a database restoration(or initial load). After the restoration or inital load you just need your cloud database copy up to date. So, for this purpose the database logs which is generated on the source database systems are being applied on target database systems until you decide to switch cloud database systems.
PS: Of course, data volume is another critical aspects of database migration to the cloud.
I want to change the status of my Azure SQL Database to offline, but cant see a way to do it from the management portal.
Thanks for reading :-)
You can add a firewall setting to deny all the IP addresses, your won't get double billed and your database is intact. The other option is rename but I wouldn't go with it unless needed.

For those who are looking to pause the Azure SQL Database to save money, now there is also a vCore-based purchase model for SQL databases in Azure.
After choosing vCore-based billing, you need to choose between:
Provisioned: Compute resources are pre-allocated. Billed per hour based on vCores configured.
or
Serverless: Compute resources are auto-scaled. Billed per second based on vCores used.
If you choose "Provisioned" you can enable "auto-pause" where the database automatically pauses if it is inactive for the time period specified (eg. 1 Hour or more), and automatically resumes when database activity recurs.

Currently, there is no way to take a database "offline" without deleting the database. A few alternatives are deleting the database and then restoring it at a later day (7, 14, 35 days) depending on the edition of the database (basic, standard, premium) respectively or exporting the database to Azure storage and then restoring at a later date.
For purpose of reducing the expenses you can downscale your database to S0 tier, which allows for same 250Gb as S3 and will cost just 15$ per month.
If you have a premium database with size more than 250Gb, than you can export it to a .bacpac and just delete / re-import. But this actually takes a lot of time and is hard to automate.
Denying all IP-s will not prevent billing AFAIK.
Do we have any standard way of daily backing up SQL Azure databases to onprim?
I know about the option of making backups to Storage, but on a daily basis, if we backup on storage blobs we will end up having many files and it will incur a high cost with Azure.
We need to take backup of SQL Azure Databases directly to onprim disks.
Maintain only two latest backups on the disk.
Do we have mechanism to schedule daily backup to storage blob and maintain only two copies at any moment of time?
Not sure if the new SQL Database Point-in-time feature is good to you. You need to enable this preview feature and select a new edition when creating your database. "Basic" edition support daily backup stores in the past 24 hours while "Standard" and "Premium" editions provides point-in-time backup stores backups in the past 7 days and 35 days.
Alternatively you need to pragmatically backup the database in blob and remove the old ones through worker role, scheduler, webjob.
Trying to design our DB backup strategy for SQL Azure. In the first instance transactions will be about 200/day.
Scenarios I will be protecting against is:
1) Complete DB lost, failure, corruption which is essentially covered by SQL Azure's saving to 3 point policy ie it has 1 primary and 2 secondary copies.
2) Corruption of records, by buggy code or user error. I would not want to restore a DB for this, and my current thoughts are use a DB copy from a "previous period" (maybe previous night) and do a data compare. Tool in mind is SQL Server Data Tools are used in VS.
My current thoughts are once a day over night take a DB Copy ie
Create Database as copy of liveDB
I think MS talks about a rolling 3 copy procedure, in my case 3 days of backup would be kept then copy 1 would be overwritten by copy 4.
Also do a DB Export as recommended by MS.
Thoughts?
Since the question was "thoughts?" here are some:
Be advised, a DB Export via the Azure managment pages produces a BACPAC which is not transactionally consistent (see http://msdn.microsoft.com/en-us/library/hh335292.aspx).
A DB Copy as you expressed above (Create Database as copy of liveDB) is transactionally consistent, but when it is finished it is billable as it will have the same edition and database size as the source database (see http://msdn.microsoft.com/en-us/library/azure/ff951631.aspx).
As JuneT mentions, using an Automated Export is transactionally consistent, because it first creates a DB Copy, then does a DB Export. Because databases are billed in increments of a day no matter how long the copy is online, if you had a daily backup, you would be paying double the cost of your source database because of the copy coming online before the BACPAC is produced. Once the BACPAC is produced the copy is no longer needed by Automated Export, but you'll still be charged for a prorated day of use. Your retention settings will also impact billing as it relates to storage accounts since you'll be paying for stored BACPACs in terms of their size.

SQL Azure has a built-in feature for restoring from this sort of issue:
see http://msdn.microsoft.com/en-us/library/hh852669.aspx
All Azure SQL Databases are automatically backed up, and the recovery options vary based on the edition of the database. Basic databases allow you to restore the database back to a its state when it was last backed up (once per 24 hours).
Standard and Premium edition databases allow restore to any point in time.
I would like to save my backups from my SQL 2008 server to another server location.
We have 2 servers:
Deployment server
File Server
The problem is that the deployment server doesn't have much space. And we keep 10 days backups of our databases. Therefore we need to store our backups on an external "file server". The problem is that SQL doesn't permit this.
I've tried to run the SQL 2008 service with an account that has admin rights on both pc's (domain account), but this still doesn't work.
Any thoughts on this one.
Otherwise we'll have to put an external harddisk on a rack server and that's kinda silly no?
EDIT:
I've found a way to make it work.
You have to share the folder on the server. Then grant the Development Server (the PC itself) write permissions. This will make external backups possible with SQL server.
Don't know if it's safe though, I find it kinda strange to give a computer rights on a folder.
You can use 3rd party tools like SqlBackupAndFTP
There are several ways of doing this already described, but this one is based on my open source project, SQL Server Compressed Backup. It is a command line tool for backing up SQL Server databases, and it can write to anywhere the NT User running it can write to. Just schedule it in Scheduled Tasks running with a user with appropriate permissions.
An example of backing up to a share on another server would be:
msbp.exe backup "db(database=model)" "gzip" "local(path=\\server\share\path\model.full.bak.gz)"
All the BACKUP command options that make sense for backing up to files are available: log, differential, copy_only, checksum, and more (tape drive options are not available for instance).
you might use a scheduler to move backups after a certain amount of time after the backup started with a batch file.
If I remember correctly there's a hack to enable the sql server to back up on remote storage, but I don't think a hack is the way to go.
Surely the best possibility may be to use an external backup tool which supports the use of agents. They control when the backup starts and take care of the files to move around.
Sascha
You could create a nice and tidy little SQL Server Integration Services (SSIS) package to both carry out the backup and then move the data to your alternative file store.
Interestingly enough, the maintenance plans within SQL Server actually use SSIS components. These same components are available to use within the Business Intelligence Design Studio (BIDS).
I hope this is clear but let me know if you require further assistance.

My experiences older versions of MSSQL, so there may be things in SQL2008 which help you better.
We are very tight on disk space on some of our old servers. These are machines at our ISP and their restore-from-tape lead time is not good - 24 hours is not uncommon :( so we need to keep a decent online backup history.
We take full backup on Sunday, differential backup each other night, and TLog backups every 10 minutes.
We force Tlog backups every minute during table/index defrag and statistics update - this is because these are the most TLog-intensive tasks that we run, and they were previously responsibly for determining the size of the standing Tlog file; since this change we've been able to run the TLog standing size about 60% smaller than before.
Worth watching the size of Diff backups though - if it turns out that by the Wednesday backup your DIFF backup is getting close to the size of the Full backup you might as well run a Full backup twice a week and have smaller Diff backups for the next day or two.
When you delete your Full or Diff backup files (to recover the disk space) make sure you delete the TLog backups that are earlier. But consider your recovery path - would you like to be able to restore last Sunday's Full backup and all Tlogs since, or are you happy that for moment-in-time restore you can only go back as far as last night's DIFF backup? (i.e. to go back further you can only restore to FULL / DIFF backup, and not to point-in-time) If the later you can delete all earlier Tlog backups as soon as you have made the DIFF backup.
(Obviously, regardless of that, you need to get the backups on to tape etc. and to your copy-server, you just don't have to be dependant on tape recovery to make your Restore, but you are losing granularity of restore with time)
We may recover the last Full (or the Last Full plus Monday's DIFF) to a "temporary database" to check out something, and then drop that DB, but if we really REALLY had to restore to "last Monday 15-minutes-past-10 AM" we would live with having to get backups back from tape or off the copy-server.
All our backup files are in an NTFS directory with Compress set. (You can probably make compressed backups direct from SQL2008??, the servers we have which are disk-starved are running SQL2000). I have read that this is frowned upon, but never seen good reasoning why, and we've never had a problem with it - touch wood!
Some third-party backup software allows setting specific user permissions for network locations. So it doesn't matter what perrmissions SQL Server service account has. I would recommend you to try EMS SQL Backup, which also supports backup compression 'on fly' to save storage space.
