We recommend following the best practices listed below to ensure that your backup archives stay healthy, accessible, and up to date.
Check your backup status report emails
Our CrashPlan for Small Business backup status reports will alert you to any issues with your backups and give recommendations on how to resolve them. The backup status report will also show specific statuses to indicate when backup has taken place.
Last backup activity indicates the last date backup activity of any kind was detected on your device.
Last completed backup indicates the last date a backup reached 100% completion to the specified destination. If there are multiple backup sets backing up to the same destination, the date shown corresponds to the most recent backup set that completed.
For more information, see Your CrashPlan for Small Business backup report
Review your frequency and version settings
CrashPlan for Small Business maintains frequency and version settings for your backup that determine how often backup will run and how long a specific version of a file will be kept. We recommend using the default settings for best performance and backup coverage.
For steps on how to view or change your frequency and versioning settings, see Specify version settings
Review your file selection
The Code42 app is designed to protect your user files. In other words, the files you create, edit, and access that allow you to get your job done. They also include certain files created by applications based on your information and settings in those programs.
The Code42 app isn't designed to back up system and application files and we don't recommend adding these files to your backup selection. Doing so could cause issues with the priority and status of other files you want backed up.
- System files are files that your device needs to work correctly. They may be a part of your operating system, a third-party device driver, or another source. Typically, you don't interact with these files directly.
- Application folders contain the files that allow various applications—like your email, word processor, and web browser programs—to work correctly. Like system files, you don't typically interact with these files directly.
Backing up only the files you need allows backups to complete more frequently. Choosing specific files and folders to include means you can be confident that your important files are protected at all times. To view your file selection or make changes, see Change the file selection
Keep your files on your device
When it comes to deciding on a backup strategy, experts recommend the "rule of three" - three copies of your data in at least 2 different locations. CrashPlan for Small Business accomplishes this by backing up your files to our secure cloud and also offers the ability to back up to local external drives.
While it may be tempting to delete files on your computer to free up space and rely on your CrashPlan for Small Business cloud or local backup, this compromises your backup strategy and puts your data at risk.
- In the event of a drive failure or file corruption, there is a chance that a file could become unrecoverable. CrashPlan accounts for this by running regular archive maintenance and re-uploading a new version of a file if needed, but this can only occur if the original file remains on your computer.
- If CrashPlan runs a scan on your device and can't find a file, that file is marked as deleted. CrashPlan for Small Business retains deleted files for a maximum of 90 days, which means that files deleted from your device will also be deleted from CrashPlan after 90 days from when they were last seen.
