Salvan Katukaran here, and welcome to another insightful session of CPM Insights. Today, we're taking a slight detour from our usual Oracle and tech-related discussions, although the relevance remains paramount. In this episode, I want to address a common yet often overlooked aspect of our digital lives—data backup.
Indirectly tied to our daily routines, this topic gained my attention when a personal experience unfolded before my Christmas vacation. My external hard disk, a repository of vital data, took an unfortunate plunge and crashed. As someone who employs VirtualBox for various projects and experiments, I was storing these virtual environments on the external drive. Alas, the crash wiped away a significant pet project that contained over 5000 lines of code and multiple components—a loss that stung.
The crash triggered a shift in my approach. I decided to bid farewell to VirtualBox, opting to install OneStream software directly on my local machine. However, a new challenge arose—how to automate SQL Server backups and effectively store them on the cloud. The journey toward a solution led me to an interesting path, where PowerShell emerged as the hero of the hour.
Before delving into the technicalities, it's worth mentioning that some colleagues and friends suggested leveraging cloud providers for a more secure and convenient approach. While this was sound advice, my decision was influenced by a few factors. The sheer size of my virtual machines and the lengthy upload process made me hesitant to embrace cloud storage immediately. However, the ordeal spurred me to explore a more efficient method—one that I could control and automate.
My exploration led me to PowerShell and OneStream's ShareFile integration. PowerShell's power in automating tasks aligned perfectly with my needs. The ShareFile integration, albeit challenging at first, opened doors to seamless file copying and archiving. This combination marked the turning point in my quest for a reliable data backup strategy.
Let's dive into the specifics. First, I needed to download a ShareFile PowerShell SDK, which enhances PowerShell's capabilities with ShareFile integration. This SDK streamlined the file copying process and introduced a range of functionalities beyond simple copying.
The process of backup and cloud storage began with creating a PowerShell script. The script kicked off by loading the ShareFile snap-in and then proceeded with executing the SQL Server backup. A crucial step was to generate a timestamp, which played a vital role in organizing and archiving the backups. Additionally, I incorporated an archiving feature that automatically deleted files older than a day—a flexible configuration tailored to individual preferences.
The beauty of PowerShell lies in its flexibility and adaptability. By leveraging SQL Server Management Objects (SMO), I was able to automate the backup process, manipulate files, and ensure that my critical data remained secure and accessible.
Our exploration today serves as a reminder that data backup is an integral aspect of our digital lives. With the right tools and strategies in place, we can mitigate risks and safeguard our endeavors against unforeseen events.
Stay tuned as we navigate through the realm of technology, exploring new avenues and unraveling the intricacies that shape our digital landscape.

Automating SQL Server Backups and ShareFile Copy with PowerShell
Greetings, fellow tech enthusiasts! I'm Salvan Katukaran, and I'm excited to dive deeper into our journey of data management and automation. In this installment of CPM Insights, we'll continue our exploration of PowerShell's prowess, particularly in the realm of SQL Server backups and seamless cloud integration using OneStream's ShareFile.
Previously, we embarked on a mission to automate SQL Server backups while ensuring a secure and efficient way to store these backups on the cloud. Today, I'll guide you through the intricate yet rewarding process that underpins this endeavor.
As we delve into the technicalities, let's demystify the PowerShell magic step by step. To begin, I needed to load the appropriate assembly, which serves as the bridge between PowerShell and SQL Server. Since my SQL Server is local, I loaded the assembly directly into the script.
Next comes the meat of the operation. I create a SQL Server object that encapsulates the instance, followed by a database object to fetch information about all databases on that server. The heart of the backup operation resides between lines 22 and 52. In this segment, I loop through each database, excluding system databases to avoid unnecessary backups.
A crucial part of this process is handling backups. To create a backup, I initialize a backup object, define its action as a database backup, and assign a unique name with a timestamp. This timestamp acts as a key identifier for the backup files. The actual backup operation involves specifying the database, adding compression, and specifying the backup device—a disk in this case. The script adds the backup device to the SQL Server backup folder, generating a backup file with the designated timestamp and '.bak' extension.
In the interest of conserving space and maintaining organization, the script compresses the '.bak' file into a '.zip' archive (lines 38 to 40). Once the compression is complete, the original backup file is deleted, leaving behind only the compressed archive.
To log the operations and ensure proper error handling, the script generates informative output messages and uses a try-catch block to catch any exceptions. This thorough approach ensures that even if something goes awry, you'll have insights into what happened and why.
Moving on to the ShareFile integration—before diving into the script, we first need to install ShareFile PowerShell SDK, which empowers PowerShell to interact seamlessly with ShareFile. Armed with this SDK, I created an authentication file that securely stores credentials and authentication information.
To initiate the ShareFile interaction within any script, I utilize the created client authentication file. This streamlined approach enables quick and secure access to ShareFile services.
The script then proceeds to create a ShareFile drive, providing a temporary workspace for the script's duration. Once the script completes, the ShareFile drive is automatically removed, leaving no trace of its existence.
In the final stages, the script identifies the user's home folder, where the backups will be copied to, and from there, the SQL backups are copied to ShareFile. Importantly, the script's design allows for flexibility in copying either the entire backup folder or just the files within.
As we navigate this intricately designed journey, keep in mind that PowerShell is a versatile tool that empowers us to automate and streamline even the most complex tasks. The combination of SQL Server and ShareFile integration showcases the potential for efficient and secure data management.
In our next installment, we'll explore advanced aspects of PowerShell and its applications in data manipulation and automation. Until then, stay curious, stay eager to learn, and let the power of technology continue to guide us toward innovation.
