rsync - using a --files-from list to cut out scanning. How to handle deletions?
Folks,
We use rsync extensively for protecting data by making backups.
Thank you to the authors and maintainers.
Like many others, we use the --link-dest option to cut down on the space
occupied by the backups.
Unlike many others, we re-cycle old backup directories. Since most file
systems change only slowly (ours average about 0.5% of files and about
1.5% of data being churned each day), a

Recycling and keeping backups - Tower of Hanoi management of backups using rsync
Thanks to Kevin and Paul for responses.
We use a modified Tower of Hanoi scheme (on top of rsync and --link-dest
and recycling) for deciding which backups to keep.
Here is a sample of our holdings for one area:
home.20111124.seq.0 set 0
home.20130512.seq.512 set 10
home.20140203.seq.768 set 9

[patch] link-dest messages and max-size warnings (fwd)
rsync Folks,
The following explanatory text is by me and the patches are by Rowan
McKenzie for use by the Advanced Scientific Computing group at CSIRO.
This patch builds upon the --link-dest patch by Bryant Hansen (Thanks heaps!).
1. The original patch provided an alternate behaviour for rsync when
using the --link-dest option.
When there are identical files in the source and link-dest areas,

Changed attributes for a file in destination that is hard linked get propagated to --link-dest directories
Folks,
Thinking again about the issue of
changed attributes for a file in source that is identical in content
to a file in destination that is hard linked get propagated to the
--link-dest directories
I would like to suggest a new flag, (perhaps called something like
--preserve-linked-attributes), to allow callers to get the
behaviour that is needed to allow the use of recycled

How do you handle snapshotting? or do you leave that to the block/fs virtualization
layer?

Multiple errors from rsync - later 'soft' error raised rather than earlier 'hard' error.
Peter,
I was about to post the below to the rsync mailing list, but wondered whether your code which captures rsync output may have allowed rsync to continue past what I think would normally be a fatal error?
Thanks
Rob.
P.S. Should I put the final backups of the old pearcey /home back into their correct slots - 5 backups were recycled, but nothing was added to them? The .Snapshots area is

Patch for rsync --link-dest won't link even if existing file is out of date (fwd)

We faced a similar situation to that which Ken described - we recycle
backup directories, for good reason.
There is a patch to solve the problem.

rsync - detecting change/no-change without an itemised list
rsync watchers,
I've been using rsync version 3.1.1+, and do like the improved --stats
output: e.g.
Number of files: 2480403 (reg: 2034290, dir: 233487, link: 212174, special: 452)
Number of created files: 356 (reg: 6, dir: 3, link: 347)
Number of regular files transferred: 16

- thanks to the developers.
However, I want to be able to look at the --stats output and make a

explict sharing of symbols between packages
Hi everyone,
I'm thinking about breaking up a large package I have to
avoid loading some of the more specialised parts when it
isn't necessary.
The package is dependent on shared libraries. The base one
will keep all of the core stuff like constructors etc and
the specialised parts will need to access these. It is
obviously possible to set the "local" flag to false, however

savehistory directories and quitting R (PR#2038)
Thanks-- as Duncan Murdoch also noted, R_HISTFILE can be used to solve my
problem, as below. BTW it's not easy to find out about R_HISTFILE in the
help system or manuals, though, unless you already know it exists-- it only
seems to be described under startup options, not things to do with history.
However, Duncan's reply did hint at an inconsistency, in that savehistory()

silent recycling in logical indexing
Sorry if this has been covered here somewhere in the past, but ...
Does anyone know why logical vectors are *silently* recycled, even
when they are incommensurate lengths, when doing logical indexing? This
is as documented:
For ?[?-indexing only: ?i?, ?j?, ?...? can be logical
vectors, indicating elements/slices to select. Such vectors
are recycled if necessary to match
