Hello rsyncers!
PRACTICAL CIRCUMSTANCES:
Backup1 shall be identical to Original. My traditional custom. NO HELP
NEEDED for this.
Backup2 shall only be a subset of the original, only files with a
certain maximum size and filename/suffix pattern get included. For
this I use rsync's filename filters and size limitations! HELP NEEDED
here! Thanks!
QUESTION:
Is there a possibility, so that --max-size AFFECTS --delete actually?
Situation where it makes sense: Imagine that I had the rule --max-
size=1M and my backup-storage is satisfying. But one day it ain't
enough anymore, and I decide to lower down to --max-size=512K. The
files larger than 512K at the destination DO NOT GET DELETED!
Currently the only solution is to rm -r /my/backup/* and then start
the process again with the new size limitations.
The manpage of rsync 3.0.6 for option --max-size reads:
[...] This option is a transfer rule, not an exclude, so it doesn't
affect the data that goes into the file-lists, and thus it doesn't
affect deletions. It just limits the files that the receiver requests
to be transferred. [...]
The content of this newsgroup post, makes me think, that in earlier
versions --max-size may have once AFFECTED --delete:

## INCLUSION LIST
### 1a) Include all dirs (so that rsync can recurse down).
+ */
### 1b) Exclude special Mac OS X dirs (bundles). They may contain
files with valid suffixes! Hence, already exclude them before they can
get a chance of inclusion.
- *.app/**
### 2a) Include all desired suffixes.
+ *.txt
+ *.text
+ *.rtf
+ *.doc
+ *.docx
+ *.htm
+ *.html
+ *.xhtml
+ *.xml
+ *.wiki
+ *.mathpad
### 2b) Include all files without suffixes (those which do not contain
a dot). Important on Mac OS X, for those files which still use
resource forks or type/creator for file type determination. And also
important for Icon files.
+! *.*
### 3) Exclude anything (else the inclusion list).
