Hello folks,

I'm using Bareos Always Incremental Scheme with the settings:

Job {
   ...
   Pool = "aincr30d"
   FullBackupPool = "aicons30d"
   Accurate = Yes
   AlwaysIncremental = Yes
   AlwaysIncrementalJobRetention = 1 months
}

Pool {
   Name = "aicons30d"
   LabelFormat = "aicons30d-"
   MaximumVolumeJobs = 1
   MaximumVolumeBytes = 50 g
   VolumeRetention = 1 months 1 weeks 3 days
   VolumeUseDuration = 23 hours
   Storage = "File"
   AutoPrune = No
   Recycle = No
}

After the 1 months daily incremental backups the daily consolitation started. Each day a Virtual Full backup job was created.
But the Virtual Full is each day a Full size backup, so the disk space is 
getting lower and lower.

This is exactly what is expected.
Please read the documentation describing it and how the "max full age" can 
solve the problem:

https://docs.bareos.org/TasksAndConcepts/AlwaysIncrementalBackupScheme.html#enhancements-for-the-always-incremental-backup-scheme

You also need to make sure that you use a new volume every day ("volume use duration"), so that jobs being removed from the database also will lead to media being recycled.

Will the option "Always Incremental Max Full Age" (for example with the setting '1 months 1 day') solve this problem? Only a virtual full backup after the specified time period? And will the initial full backup also be released for deletion?

Thanks Ralf
