Overview
Sometimes it may take a bit longer than you would expect to restore a file from a backup set on the Code42 app. This article explains the steps the Code42 app takes to restore a file to a your device, external factors impacting network speeds that are outside Code42's control, and tips for improving file restore speeds.
Before you begin
Review How backup works. Restoring a file reverses this process.
File restore process
To restore a file, the Code42 app:
- Accesses the archive index to locate the blocks of data that make up the file you want to restore.
- Reassembles the relevant blocks to recreate the file.
- Retrieves the file and downloads it to your device.
- Decompresses and decrypts the file back to its original state.
Because these steps reduce the amount of data to transfer while keeping files secure, restoring a file generally takes more time than a simpler file download.
Factors affecting restore speeds
File size and one-at-a-time processing
The Code42 app restores and downloads files one-at-a-time, and the size of the files in the queue can slow the restore process. When restoring a large file, the estimated time of completion for that file's restoration can fluctuate and can impact the time it takes to restore multiple files.
If the restoration of a large file is interrupted, the Code42 app restarts that restore from the beginning. The Code42 app cannot resume a file restore from when the process was interrupted. Preventing the device from entering sleep mode and ensuring a stable network connection helps the restore process for large files complete smoothly and as quickly as possible.
Microsoft Outlook data files
Microsoft Outlook saves your email messages, calendar, tasks, and other items in either an Outlook for Windows Data File (.pst) or an Outlook for Mac Data File (.olm). Because these files are updated throughout the day as you receive emails or schedule meetings, the Code42 app backs up Outlook data files using the Volume Shadow Copy Service (VSS) on Windows or an exported .olm file on Mac. In some cases, these files can become quite large. Large Outlook data files or issues encountered during their backup can affect how long it takes to restore such files.

Bandwidth and external factors affecting speed
What you can do
- For Outlook data files or other large files, consider creating a backup set with settings optimized for just that file. These optimized settings may help the restore process move more quickly.
- Restore large files in off-hours, when networks are less busy.
- Change the device's power plan to the high-performance mode, or adjust the power settings to enable higher performance. Preventing the OS from putting apps to sleep and allowing it to run at the highest speeds can help restores run without interruption.
