Is there any way to do Azure Table Storage backup in to an another Azure Table Storage incrementally. AZcopy has solution for full backup for the table but not incremental.
We don’t not support backup of Azure Tables currently, and we may not be doing that in the near future
Going forward future Table investments will be in Cosmos DB. See the documentation for Azure CosmosDB online backup and restore
There is a similar thread discussion in the SO link, this provides some idea on your scenario

I want to take an Archival(Backup) of Azure SQL Table to the Azure Blob Storage, I have done the backup in Azure Blob storage using via the Pipeline in CSV file format. And From the Azure Blob Storage, I have restored the data into the Azure SQL Table successfully using the Bulk Insert process.
But now I want to retrieve the data from this CSV file using some kind of filter criteria. Is there any way that I can apply a filter query on Azure Blob storage to retrieve the data?
Is there any other way to take a backup differently and then retrieve the data from Azure Storage?
My end goal is to take a backup of the Azure SQL table in Azure Storage and retrieve the data directly from Azure Storage with a filter.
Note
I know that I can take a backup using the SSMS, but that is not a requirement, I want this process through some kind of Pipeline or using the SQL command.
AFAIK, there is no such filtering option available when restoring the database. But, as you are asking for another way to backup and restoring, SQL Server Management Studio (SSMS) is one the most conveniently used platform for almost all SQL Server related activities.
You can use SSMS to access Azure SQL database using server name and Login Password.
Find this official tutorial from Microsoft about how to take backup of your Azure SQL Database and store it in Storage account and then restore it.
In my azure subscription I have a storage account with a lot of tables that contains important data.
As far as I know azure offers a backup point-in-time for the storages and blobs, and geo redundancy in event of a failover. But I couldn't find anything regarding the backup of table storages.
The only way to do so is by using azCopy which is fine and a logic, but I couldn't make it work as I had some issues with permissions even if I set the Azure Blob Data Contributor to my container.
So as an option, I was thinking if there is a way how to implement this using python code to loop throu all the tables in a specific container and make a copy into another container.
Can anyone enlighten me on this matter please?
Did you set the Azure Storage firewall: allow access from all networks?:
Python code is a way but we can't help you design the code. And there isn't an example for you. It doesn't meet Stack Overflow's guideline.
If you still couldn't figure it out with AzCopy, I would suggest you think about use Data Factory to schedule backup the data from table storage to another container.
Create a pipeline with copy active to copy the data from Table
Storage. Ref this tutorial:Copy data to and from Azure Table
storage by using Azure Data Factory.
Create a schedule trigger for the pipeline to make the jobs
automatic.
If the Table storage has many tables, the easiest way is using Copy Data Tool.
Update:
Copy data tool source settings:
Sink settings: auto create the table in sink table storage
HTH.
I'm new for Azure, Do we have any default job to perform database backup from Azure Tabular storage?.
Do we have any default job to perform database backup from Azure Tabular storage?.
No, we do not have default job to do it.
Huge demand to backup data directly from the azure Blob/table storage accounts. In order to meet compliance- today users have to move the data to VM and then back it up. This will simplify the current process to take the backup, meet the compliance and BCDR requirements and also save on Cost.
You can give your voice to this feedback to promote the further to achieve. Or you can refer to this issue to manually backup your table storage.
My Azure WebApp stores data in Azure Storage Tables and Blob storage.
There is a backup functionnality, but as I understood it just does not support azure tables/blobs... however I would like to automatically backup my tables to protect against accidental data corruption by users or by a software issue...
I would like to backup MyProdTables in MyBackupBlob container. Is there away to do it actually?
I read something about AZCopy, but it seems working with virtual machine's hard drives, but we have the WebApplication as a Service, so I am not sure that it will work in our case...
Edit: There is a partial (negative) MS feedback on the question, as mentioned in this answer, but it focused rather on migration and entire account snapshots. I am rather focused on the table storage, and maybe even the possibility of backuping individual tables... is strange that is nothing possible in this field, cause MS Azure Storage Explorer can easily backup the tables as CSV files.
There is no built-in backup feature for blobs and tables, as you've surmised. However: blobs do offer snapshots (a point-in-time snapshot may be taken at any time).
There are also Shared Access Signatures (and Policies) to limit exposure to your storage. And you can even protect the storage account itself from deletion.
As for AzCopy: that has nothing to do with VM disks. That's specifically for moving content in and out of blobs and tables.
I want to confirm our understanding of how our Azure SQL databases are being backed up to enable point in time restore. We have not currently configured geo-replication to have the database available in another region. We may in the future as some data analysis is done. But my understanding is that the database is still being backed up to a geo redundant location so I could do a geo-restore if there was an issue with the data center that houses my sql database. Is that correct or do I need to enable geo-replication and pay for a second database in order to have a disaster recover option if the datacenter had an issue.
To clarify further: I think this article states what I'm saying in the Geo-Restore section.

Yes, all databases have a geo-replicated copy for disaster recovery purposes. For more details, please see the following: https://azure.microsoft.com/en-us/blog/azure-sql-database-geo-restore/
Geo-restore uses the same technology as point in time restore with one
important difference. It restores the database from a copy of the most
recent daily backup in geo-replicated blob storage (RA-GRS). For each
active database, the service maintains a backup chain that includes a
weekly full backup, multiple daily differential backups, and
transaction logs saved every 5 minutes. These blobs are geo-replicated
this guarantees that daily backups are available even after a massive
failure in the primary region.
Yes, Azure SQL Databases are automatically backed up to a different Azure data center using Geo-Replication. This is an automatic features of Azure SQL that is baked into the service offering.
