Backup, Recovery and Replication

This section provides a comprehensive guide for setting up recovery between two ZS3Servers.
This setup uses the Blimp UI for deployment, Visual Studio Code for configuration, and MinIO Client (mc) for management.
Whether you're new to ZS3Server or an experienced user, this guide offers detailed instructions for every stage of the process.
Go to "Manage Allocations" and select "S3 Setup." and click on create new allocation
Now add blobbers and Click on "Confirm" to add blobbers. Review and confirm the details and pay from the existing balance. Create an allocation and the S3 server setup will open automatically. You will have to create your server instance by adding IP address.
You need to obtain the IP address of your server, which can be provided by your hosting provider or retrieved using the ifconfig command in the terminal. For example, in the server logs, you may see an IP address such as 65.109.152.43.
Now add your IP address and click on generate script in Blimp UI. Then enter the password for S3 deployment.
Now copy the script and run it in your server terminal.
Go to "Standard Allocation" in the Blimp UI. Create a new allocation and name it allocation22.
Click on "Confirm" and select the blobbers, then confirm again. This will create a standard allocation.
In the Blimp UI, copy the newly created standard allocation ID.
Go to your server, create a new .zcn2 folder in your home directory ($HOME), and navigate to the blimp folder. Inside the blimp folder, create the allocation.txt file and paste the allocation ID.
Copy the docker-compose.yml, config.yaml, wallet.json and z3server.json files from the .zcn folder to the .zcn2 folder.
Edit the ports in docker-compose.yml.Go to line 55 in the .zcn2/docker-compose.yml file and note the ports 9002:9000. Copy these ports to the .zcn/docker-compose.yml file.
Now run the following commands to start the Docker containers for .zcn2 folder defined in the docker-compose.yml:
Change the first port in .zcn from 9002 to 9000 in docker-compose.yml file, making it 9000:9000.
Now run the following commands to start the Docker containers defined in the docker-compose.yml:

Run the following command to create an alias for zs3server1:
Run the following command to create an alias for zs3server2:
Create a bucket in zs3server1 with allocation21:
Verify the bucket:
Copy data to the created bucket:
Create a bucket in zs3server2 with allocation22:
Verify the bucket:
Run the following command to create replication between the buckets:
Any deletions in bucket1 will automatically replicate in bucket2.
Shut down zs3server1 and clean up its deployment.
Create a new allocation (allocation23) using the Blimp UI with a standard allocation.
Update the allocation.txt file in .zcn with the new allocation23 ID.
Set up an alias for the new server:
Create a new bucket:
Restore data to the new allocation:
Check that the files have been recovered to the new allocation:
This section outlines the steps to set up replication between two ZS3Servers.
Replication ensures that data from one server is mirrored to another for backup and redundancy.
Follow the steps below to configure and initiate replication.
For running two ZS3Servers on the same machine:
Copy the contents of the .zcn folder to .zcn2.
Update allocation.txt and zs3server.json in .zcn2.
Update the docker-compose.yml file to use unique ports.
Ensure both ZS3Servers are configured using MinIO Client aliases:
Alias for the first server (zcn):
Alias for the second server (zcn2):
Navigate to the .zcn2 folder:
Open the terminal and run:
Verify the ports are correctly set to 9002:9000.
Check the standard allocation ID:
Compare this ID with the allocation ID in the Blimp dashboard to ensure consistency.
Use the MinIO Client (mc) to configure aliases for both servers:
Format:
Example:
Run the alias commands:
Use the following command to start replication:
Replace <BUCKET_PREFIX> with the appropriate bucket names.
Example:
test2-s3 is a folder in the S3 allocation.
mbtest2 will be created in the standard allocation on zcn2.
All data from test2-s3 will be replicated into mbtest2.
Check the contents of the buckets:
Create new buckets if necessary:
Confirm that the data is mirrored correctly:
Use crontab -e to add periodic backup jobs.
Follow the installation guide provided in the .
Install mc packages using
Use for lightweight, versioned, and secure backups to your ZS3 bucket.
