Within the Web GUI of BackupPC are no differences bwetween incremental or
full backups. Each backup number will display always all files containing to
this backup independent if they are stored during the actual incremental or
a previos incremental or a previous full.
If you are using rsync than the only difference between full and incremental
are:
- incremental only scan files which are created after the last backup.
Therefore it is a lot faster than a full backup.
- full backup scan all files, also files which would be extracted from an
archive after the last backup but have an extracted timestamp older than
the last backup.
Therefore a full is much slower but get really all "new" files.
I do a full every week and incrementals every day. I keep the incrementals
for 14 days, the weekly fulls for 8 weeks and the monthly fulls for a year.
