Backing up Azure file storage to Azure Backup

Iron Contributor

Hi Team,

 

We are already using Azure file Storage. This is to copy files directly to Azure Storage (file shares). A virtual drive has been mapped for this storage.

Since Azure File Storage does not support Recovery/Restore Points (i.e. restore a file one week old) or Point in Time copies, we need to use Azure Backup which has these Point in Time/Recovery Points capabilities which will allows us to restore files like 2 days old in case a file has been delete or overwritten.

Per our research, Azure File Storage backed up directly to Azure Backup is not possible (yet).

Backup of Azure Storage is only possible on BLOB Storage but not Azure File Storage. See links below.

https://docs.microsoft.com/en-us/azure/backup/backup-try-azure-backup-in-10-mins

 

Is there any possibiltity to achieve this with current capabilities or if not, has this been taken in to the timelines for future deliveries ? any feedback is really appreciated !

 

Thank You

Hi Team,

 

I'm new to Azure and Azure services, i have one query regarding Azure Backup service.

 

Since Azure backup will take incremental backup, i'm setting up my retention policy as 10 days.

Daily it takes incremental backup, an new .vhd file is created and mapped with my first full backup.

 

If suppose i'm adding an new file(named - test123.txt) on the 5th Day and after that i have not made any changes in it. so it will be on the 5th day incremental backup vhd file only.

Now coming to retention period, on the 16th day my 5th day incremental backup vhd file will be deleted.

 

1. Does i can retrive my test123.txt file from the backup??? 

2. Does Azure backup will take symentric full backup???

3. to retrive my test123.txt file what are the steps i need to follow???

4. Azure backup does not take full backup and differntial backup daily???(True/False)

Here are my responses to your questions: 

 

1. Does i can retrive my test123.txt file from the backup??? 

[A] Yes you can. Azure Backup uses snapshotting mechanism for backups. Since Azure Files supports incremental snapshots,

 a. Files (or blocks within the files) in Azure File Shares are snapshot-aware. 

 b. there is understanding of new and old files and changes within them. While your file will be on the 5th day snapshot, the 6th day snapshot will also "point" to the same file but because there was no change, there will be no incremental change in the size of the snapshot as there are no changes in the file. On the 16th day when your 5th day Snapshot is deleted, you would still have the 6th,7th till 16th day snapshots pointing to the same file, and therefore you'd be able to recover the file. Unless say on the 10th day, the file itself is deleted. In this case 11th, 12th and so on snapshots will not have a pointer to that file. 

 

2. Does Azure backup will take symentric full backup???

[A] : I guess you mean Synthetic Full. We do forever incremental and not full-backups for Azure File Shares. 

 

3. to retrive my test123.txt file what are the steps i need to follow???

[A] : Refer to this article : https://docs.microsoft.com/en-us/azure/backup/backup-azure-files#restore-individual-files-or-folders... or watch this :

Backup your data with Microsoft Azure Backup - BRK3060

 

4. Azure backup does not take full backup and differntial backup daily???(True/False)

[A] : True. We only do incremental. Only the first backup is full.
