We have the next script for restoring DB.
Rename the current DB instance (mydb -> old_mydb).
Restore a DB instance to a specific point in time in new DB instance. Restore old_mydb to mydb.
But after restoring the new DB instance doesn't have old backups and we can't restore this instance again. Are there any ways to link the old backups to the new instance?

I'm looking at creating a disaster recovery script on AWS for restoring servers.
I've written the Terraform script to create a new EC2 instance, but I'd like to restore a snapshot from the old EBS volume to a new one and then attach that to the new EC2 instance.
I've been looking through Terraform though and can't see a way to restore a snapshot to a new volume, is it possible?
I am managing an RDS Database in an CDK Project. From time to time it is necasary to recover an old state of the database from snapshot.
To make this possible, I have CDK Context Parameter specifying the Snapshot from which the Database should be recovered. If it is given, the snapshot is bassed to the RDS Construct. This leads to a replacement of the database (which is fine).
Now, if the database has been recovered from snapshot and I do some other update in the CDK Project and want to update the project (which is done via CD Pipeline) I usally start the update without giving any snapshot. This leads to the database to be replaced by an empty one, which is of course not what I want.
To summarize, this is how it currently works:
Current state of the stack
Deployment Paramter
Result
Not created from snapshot
No snapshot
DB is not replaced
Not created from snapshot
snapshot
DB is replaced
created from snapshot
No snapshot
DB is replaced
created from snapshot
snapshot (same)
DB is not replaced
created from snapshot
snapshot (different)
DB is replaced
This is IMHO not managable.
But what I want is something like this:
Current state of the stack
Deployment Paramter
Result
Not created from snapshot
No snapshot
DB is not replaced
Not created from snapshot
snapshot
DB is replaced
created from snapshot
No snapshot
DB is not replaced
created from snapshot
snapshot (same)
DB is replaced
created from snapshot
snapshot (different)
DB is replaced
Or, to put it in other words:
If I specify no snapshot, don't replace the DB
If I specify a snapshot, repalce the DB
Is this possible? Or is there another good way to manage an RDS Database using CDK?
I have a bitnami instance working fine on my AWS console. I want to make a backup of it so that if I mess something up I can simply deploy an older backup.
I followed the instructions here:
https://docs.bitnami.com/aws/faq/administration/backup-restore-server/
So I have the snapshot created. But how do I get a bitnami instance running based off of that snapshop?
That page says:
This feature creates a new snapshot of the disk, which can later be used to restore the server to an earlier state.
To restore the snapshot, you can use "Create Volume" to create a new Amazon EBS Volume from the snapshot. You could then restore the system to the state of the snapshot with these steps:
Stop the instance
Detach the current EBS volume
Attach the new (restored) EBS volume with the same device identifier
Start the instance
However, if you wish to launch a totally new instance using the backup, then the easier backup method would be:
Use "Create Image" in the EC2 console to create an Amazon Machine Image (AMI)
Launch a new instance using that AMI
My GCP SQL instance is stuck on restart. Is there way to force stop or restart or to access the database backups so I can create a new one from the backup?
After 1 hour the instance restart failed due to an unknown error.
The original instance was db-n1-standard-1. I created a new instance type db-n1-standard-2 (more memory and 2CPU) and I managed to restore a backup to the new instance.
Any other operations to restore backup or clone in the db-n1-standard-1 failed.
I made a big technical mistake when I launched my mysql database by selecting the largest storage setting by my database. As a result I deleted the instance, but I do have a snapshot of the last instance. I don't want to reinstate the snapshot and get charged, so I was wondering if there was a way for me to export the data from my last snapshot into a csv file and then create a new instance with smaller storage. Is this possible?
The only thing you can do with an RDS snapshot is restore it into a fresh RDS instance. Once you have the instance, you can export the data as CSV or using mysqldump.
From that, you can terminate the temporary instance and create your new, smaller instance and import the data.
But you cannot get at the data directly with the snapshot.
