In v4 full/incremental related to backup transfer only, filled/unfilled related to storage. Here is a short explanation: http://backuppc.sourceforge.net/BackupPC-4.0.0alpha3_doc.html#BackupPC-4.0 "Backups are stored as "reverse deltas" - the most recent backup is always filled and older backups are reconstitued by merging all the deltas starting with the nearest future filled backup and wworking backwards. This is the opposite of V3 where incrementals are stored as "forward deltas" to a prior backup (typically the last full backup or prior lower-level incremental backup, or the last full in the case of rsync)." So, the latest backup should always be filled, i.e. it actually contains all files. After the last backup will be taken, files that latest backup contains will be removed from backups between the last backup and previous filled backup recursively. Until the last backup was taken, previous backup was filled, but now it is just "reverse delta". ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
