rsync backup - order by size

[Ty Miller]

Hey Matt,

Thanks for the quick response. That sounds exactly what I am after.

I considered using the --max-size and --min-size options, but I stopped
because I didn't know how the backups would handle two passes that only look
at subsets of the filesystem.

Currently I use an enhanced version of the incremental backup script found
on the rsync site (http://samba.anu.edu.au/rsync/examples.html) - same
concept though;

- Empty the daily incremental backup dir
- Backup to the "Current" dir, moving modified or deleted files to the daily
incremental dir

If I changed this to include the --min-size and --max-size so that there are
the following two rsync passes;

- Empty the daily incremental backup dir
- Backup small files to the "Current" dir, moving modified or deleted files
to the daily incremental dir
- Backup large files to the "Current" dir, moving modified or deleted files
to the daily incremental dir

How will this affect the reality of what happens? For example;

- Will the first pass cause the Current dir to only contain small files,
causing it to move the large files to the daily incremental dir?

- Will the second pass cause the Current dir to only contain large files,
causing it to move the small files to the daily incremental dir?

- Will this second pass cause the incremental dir to only contain small
files, or will this now contain everything, or just the modified/deleted
small and large files?

Any thoughts?

Thanks again,
Ty

Rsync has no option to transfer files in order of increasing size, but
there are two ways to accomplish something similar to that.  See
