Portability and Scalability: VPS instances can be easily moved between physical servers without downtime. This portability facilitates scalability, allowing users to add or remove resources as needed.

Comparing VPS with Other Compute Options

VPS often gets intermingled with virtual machines and cloud instances. These terms essentially refer to the same concept – a virtual environment operating on a physical server using a hypervisor. The distinction lies in the terminology employed by different hosting providers.

VPS vs Dedicated Servers (Bare Metal Servers): Dedicated servers (bare metal servers) provide more computing power but come with a higher price tag.
VPS vs Virtual Dedicated Servers (VDS): VDS is a virtual machine like VPS but has more computing power assigned to it and uses both virtual and dedicated resources.
VPS vs Shared Web Hosting: Shared web hosting doesn’t offer root access and is limited to website hosting.

Feature	VPS	Dedicated Server	VDS
Root access	Yes	Yes	Yes
Dedicated resources	Yes	Yes	Yes
Portability	High	Low	Medium
Scalability	High	Medium	High
Use cases	Websites, applications, databases, gaming, email servers	High-traffic websites, demanding applications, critical infrastructure	Websites, applications, databases, gaming, email servers

Guide to Linux Server Backup Using Rclone and Object Storage

ellysha — Fri, 24 Nov 2023 07:06:24 +0000

In this comprehensive guide, we will delve into the process of creating both manual and scheduled backups of any Linux server to Object Storage using rclone. This guide caters to a wide range of Linux servers, including Dedicated Servers, VPS, and VDS. The provided commands have been thoroughly tested with Ubuntu 18.04(64 Bit), Ubuntu 20.04(64 Bit), Debian 9, and Debian 10. While these commands are primarily tailored for these distributions, slight adjustments may be required for other distributions like CentOS.

Throughout this guide, it is assumed that you have root access to the Linux server. To elevate your privileges, enter the following command:

sudo -i

Initial Linux Server Backup Configuration

Acquiring Object Storage Credentials for Backup Storage

In this tutorial, we will utilize Object Storage as our backup destination. We assume that you already have an active Object Storage subscription.

To proceed, you will need to gather the necessary credentials, including the access_key, secret_key, and URL. These credentials can be obtained from the Object Storage section of your server’s Control Panel (CCP).

Creating a Backup File on the Linux Server

Before proceeding with the backup process, we need to install the latest version of rclone using the following command:

curl https://rclone.org/install.sh | sudo bash

Next, we will create a backup of the current user and store the backup file with the current date in the /opt/backup/ directory. Execute the following command to achieve this:

mkdir /opt/backup/ cd /opt/backup && tar -cvzf backup-$(date +%d.%m.%Y).tar.gz --directory=/ --exclude=lost+found --exclude=dev/* --exclude=proc/* --exclude=run/* --exclude=sys/* --exclude=tmp/* --exclude=mnt/* --exclude=media/* --exclude=opt/backup/* .

Here’s a breakdown of the command:

tar: The tar command is used to create an archive of our data.
c: This option stands for create and indicates that we are creating a new archive.
v: This option represents verbose and provides detailed output during the process.
z: This option signifies gzip, implying that the archive will be compressed using gzip.
f: This option represents file and specifies the name and location of the archive. It must be the last option passed, as everything following f is treated as a file path.
/path/filename.tar.gz: This indicates the path where the archive will be stored.

In this command, certain directories have been excluded from the backup process due to storage space considerations or the presence of unwanted large files in the tmp directory.

Configuring Rclone on a Linux Server

For this step, we assume that the files and folders you intend to back up are stored in the /opt/backup/ directory.

If you haven’t already, follow the instructions in our product documentation to set up Rclone. Once Rclone is configured, we can proceed with the Linux server backup using Rclone.

Transferring Your Backup File from Linux Server to Object Storage

In this step, we will transfer the backup file created in step 2 to the Object Storage. Assuming you have named your object store eu2 and your backup folder backup, execute the following command to create a bucket where we will store all the files:

rclone mkdir eu2:backup

After completing the steps in the “Initial Configuration” section, run the following command to save the files to your Object Storage:

rclone copy -P /opt/backup eu2:backup/server1

This command will transfer all data from /opt/backup to the specified bucket.

Here are the available options for transferring data:

rclone copy -P /opt/backup eu2:bucketname/server1: This command copies all data without deleting the source files.
rclone move -P /opt/backup eu2:bucketname/server1: This command moves all data, deleting the source files after the transfer is complete.
rclone sync -P /opt/backup eu2:bucketname/server1: This command synchronizes the data, ensuring that the files on the server and in the bucket are identical.

Scheduling Rclone Backups

After completing the initial configuration steps, you can set up scheduled backups to run automatically. To achieve this, follow these steps:
- Create a script file: Start by creating a script file using the following command:
```
sudo nano /var/rclone.sh
```
- Add the script contents: Open the script file in the nano editor and add the following contents:
```
#!/bin/bash

# Navigate to the backup directory
cd /opt/backup

# Create a backup archive with the current date
tar -cvzf backup-$(date +%d.%m.%Y).tar.gz --directory=/ --exclude=lost+found --exclude=dev/* --exclude=proc/* --exclude=run/* --exclude=sys/* --exclude=tmp/* --exclude=mnt/* --exclude=media/* --exclude=opt/backup/* .

# Sync the backup files to the S3 storage
/usr/bin/rclone sync -P --update --verbose --transfers 30 --log-file=/var/log/upload.log "/opt/backup" "eu2:backup/"
```
- Make the script executable: To ensure the script can be executed, use the following command:
```
sudo chmod +x /var/rclone.sh
```
- Add the script to cron: To schedule the script to run at a specific time, open the crontab file using the following command:
```
sudo crontab -e
```
- Add the cron job: At the end of the crontab file, add the following line to schedule the backup script to run daily at 02:00:
```
0 2 * * * /var/rclone.sh
```
- Save the crontab file: Save and close the crontab file.

Block Storage vs Object Storage vs File Storage: A Data Storage Solutions

ellysha — Fri, 24 Nov 2023 04:38:19 +0000

In the realm of data storage, various options exist, each tailored to specific needs and usage scenarios. Block storage, object storage, and file storage are three prominent storage solutions that cater to different data types and access requirements. This guide delves into the intricacies of each storage type, providing insights into their functionality, scalability, cost-effectiveness, and optimal use cases.

Block Storage

Understanding Block Storage

Block storage, often employed for structured data, utilizes a linear arrangement of data blocks. Each block is of a fixed size, enabling rapid access and retrieval. Block storage is particularly well-suited for applications that demand quick access to large files, such as databases and virtual machines.

Key Characteristics of Block Storage

Structure: Block storage lacks a hierarchical structure, requiring manual organization of raw data.
Block Size: Each block has a predetermined, consistent size.
Scalability and Cost-Effectiveness: Block storage is more expensive than file storage due to its hardware requirements and on-premises deployment. However, it offers greater scalability for large data volumes.

Ideal Use Cases for Block Storage

On-premises or private cloud storage for large amounts of structured data.
Applications requiring rapid access to individual files.
Databases and virtual machines.

Block Storage

Exploring Object Storage

Object storage, designed for unstructured data, stores data as distinct entities called objects. Each object contains metadata and a unique identifier, enabling efficient management and retrieval. Object storage is ideal for storing vast amounts of unstructured data, such as images, videos, and backups.

Distinguishing Features of Object Storage

Structure: Object storage employs a flat structure, organizing data into buckets.
Object Size: Objects can vary in size, accommodating unstructured data types.
Scalability and Cost-Effectiveness: Object storage is highly scalable and cost-effective due to its cloud-based architecture.

Optimal Use Cases for Object Storage

Storage of large amounts of unstructured data and large files.
Data archiving and backup solutions.
Content delivery networks (CDNs) for streaming media.

File Storage

Delving into File Storage

File storage, the traditional method of data organization, utilizes a hierarchical structure of folders and subfolders. It is commonly used for storing structured data, such as documents and spreadsheets.

Defining Traits of File Storage

Structure: File storage maintains a hierarchical structure, allowing for organized data management.
File Size: File sizes can vary depending on the content and metadata.
Scalability and Cost-Effectiveness: File storage is limited in scalability due to its dependence on physical disk drives. It is also less cost-effective compared to object storage.

Appropriate Use Cases for File Storage

Storage of small to medium amounts of structured data.
Data sharing and collaboration within teams.
Storing personal files and documents.

Selecting the Right Storage Solution

The choice between block storage, object storage, and file storage depends on the specific data type, access requirements, and budget constraints. Here’s a summary of their strengths and limitations:

Storage Type	Strengths	Limitations
Block Storage	Rapid access to large files, suitable for databases and virtual machines	Expensive, requires on-premises infrastructure
Object Storage	Scalable, cost-effective for large amounts of unstructured data, ideal for backups and CDNs	Not ideal for structured data, requires cloud-based deployment
File Storage	Organized data management, suitable for small to medium amounts of structured data	Limited scalability, less cost-effective compared to object storage

Additional Considerations

Price: Evaluate pricing models and ensure transparency in billing structures.
Vendor Lock-in: Choose providers that offer data portability and avoid vendor lock-in.
Integrations: Assess the availability and robustness of integrations with existing systems.
Ease of Migration: Consider the migration process and available documentation to ensure a smooth transition.
Upkeep and Access: Evaluate the ease of data access and management within the chosen storage solution.

Conclusion

The choice between block storage, object storage, and file storage depends on the specific data type, access requirements, and budget constraints. Block storage excels in providing rapid access to large structured files, while object storage offers scalable and cost-effective storage for vast amounts of unstructured data. File storage remains a suitable option for organizing and managing small to medium amounts of structured data. Carefully evaluate your storage needs and consider the strengths and limitations of each type to make an informed decision.
