I think that while a delta is backed up, BackupPC then uses hard links to
the files from the last backup in order to fill out the backup so that it
looks like a full copy.
I also think this is part of BackupPC's pooling mechanism.
For comparison, I theoretically have 1terabyte of data backed up, but it's
actually only consuming about 120-130gigabytes of storage on my backup
server, thanks to BackupPC's data pooling.
