File System Snapshot
Cloud computers rely on a file system snapshot process as an integral aspect of maintaining performance, service availability, and disaster preparedness. Businesses that leverage cloud resources as part of their core systems understand this. A crucial element of running virtual machines is maintaining system integrity.
Since V2 Cloud runs in a virtualized environment, you need to be sure you have a file system snapshot when you make changes to your cloud desktop. These changes could be software upgrades, drive upgrades, or installing new apps. Before you do any of this, it is essential to capture a snapshot just in case you encounter an error after you perform a change.
What is a File System Snapshot?
Save storage resources easily
A snapshot is a point-in-time copy of the state of a file system. The name comes from the analogy of a photograph that similarly captures a point-in-time instance of an occasion. It captures and saves a file system state, before or after any changes have been made.
Backup only the essential data
Snapshots are important because they tell the system which data block should be preserved. Moreover, each subsequent snapshot only captures changes from the last one. An entire system timeline can be saved to ensure reliability and system continuity.
File System Snapshot vs. Backup Copy
You might wonder whether those two terms are the same. While snapshots are a form of copying a system, they differ from backup copies. Taking a backup copy saves a duplicate of all the files in the captured system. If you are making a backup copy of a cloud desktop, it will duplicate all the data on the desktop and save a copy of this.
As you can imagine, regularly saving copies could lead to massive storage requirements. On the other hand, a snapshot only saves the point-in-time state (user data and user attributes) of a file system. This leads to significantly less storage resource requirements plus faster system backups.
File System Snapshot Perks
Say goodbye to massive backup copies that take all of your storage. Discover snapshots!
Better System Reliability
Snapshots only capture system changes and not the entire system. So, if the system does not change, no snapshots are covered. This ensures better data integrity because there is a lower chance of file conflicts or data corruption due to saving the same data repeatedly.
More Detailed Captures
V2 Cloud captures only the changes in a system (also known as Delta backups). They can be set to create snapshots every time there is a system change. From this, a detailed timeline of changes can be created, helping ensure faster system restoration in case of any system failure.
System copies occupy space equivalent to the number of backups times each backup size. That is, if the system is 2GB, each backup copy will be 2GB. That's why snapshots are significantly lower and only occupy the amount of space that the changed blocks occupy.
The time it takes to capture a snapshot is significantly less than taking a backup copy. With V2 Cloud, the time and I/O needed to create the capture is not directly proportional to the file system size. For a backup copy, the time it takes to create a capture increases as the system file size increases.
V2 Cloud Backup Snapshot Solution
V2 Cloud gives you the tools you need to create reliable snapshots of your data and systems within our cloud infrastructure. If you are running cloud computers on V2 Cloud, you automatically get daily automatic snapshots up to seven days. We ensure all your machines are reliably backed up, so you never lose any data or system capabilities.
A system copy captures entire copies of your system resulting in an exponentially growing data set. Unlike it, enabling snapshots for your cloud desktop will not impact your storage requirements. Moreover, a detailed timeline of your cloud computer states ensures you can roll back changes to within hours of a failed system state.
Why do you need a backup snapshot?
Ransomware Data Recovery
Rolling back your remote desktops is easy when you have automatic backups enabled. Snapshots capture the entire desktop, including all apps running, so you can easily roll back the whole desktop in case of ransomware attacks.
High-Availability System Backups
If you run high-availability systems, file system snapshots can help you capture frozen states of your system. You can easily do this without taking the systems offline or halting write functions.
Desktop Upgrade Control
File system snapshots are crucial when upgrading desktop software. If you push an update that kills some of your apps, you can easily unfreeze the last file system snapshot and restore functionality.
Keep your data safe
Why We’re Better
Enabling V2 Cloud file system snapshot features allows you to perform all your desktop restorations in the cloud. That means you can restore machines from anywhere—no IT skills required. You can also attach some data as a disk to recover some specific data without having to backup entirely your desktop.
V2 Cloud file system snapshots offer always-on availability for all your system backups. If you have been using local backups, moving to V2 Cloud snapshots can save local disc space and give you enhanced access to your snapshots.
Enhanced Backup Portability
Since your snapshots are stored in the cloud, you can easily port them from one cloud resource to another. This means you can quickly restore your cloud desktop regardless of the infrastructure you’re using.
