CloudBerry Backup supports backup of files being in use by the default. For this purpose, CloudBerry Backup uses Volume Shadow Copy Service (VSS)
Volume Shadow Copy Service is an implemented Windows service. It allows taking snapshots of data being in use or located on a locked volume. Using VSS with CloudBerry Backup, guarantees you that all the data that is to be backed up will be backed up as it is on a moment of backup.
Volume Shadow Copy Service Limitations
Volume Shadow Copy Service has a few limitations. Because of VSS limitations, not all the data being in use can be backed up. Volume Shadow Copy Service doesn't work for network files such as network shares and mapped network drives. Also, VSS can’t make snapshots of data stored on any volume with FAT32 file system.
Due to VSS technology limitations mentioned above CloudBerry Backup can’t backup files being in use kept:
- In network shares;
- On mapped network drives;
- On any drives with FAT32 file system.
Using "Force using VSS" Option of CloudBerry Backup
CloudBerry Backup has the "Force using VSS" option. When this option is turned on CloudBerry Backup is forced to create a snapshot of all the files on a volume as they are on the moment of the backup. This is used to force backing up of files that may be locked for the time of backup.
In most cases, locked are the files that are accessed by other applications and services. And if "Force using VSS" option of CloudBerry Backup is not active such files can be backed up as they were on the point in time when they were last saved.
How to Activate “Force using VSS” Option
1. Start Backup Wizard;
2. In the "Advanced Options" step, check the Force using VSS (Volume Shadow Copy service)
Once the “Force using VSS” option is enabled all the files being in use will be backed up on each run of your backup plan. Using this option, please make sure that data you are planning to backup doesn’t meet the Volume Shadow Copy Service limitations mentioned above.
