Password:
In this place it's sit and waiting for password. If I comment out related ccollect code section everything
start working as expected. I had to modify this part to be look like:
if ! rsync "${source}" "$@" >/dev/null 2>"${TMP}" ; then
if [ ! -f "${c_quiet_if_down}" ]; then
cat "${TMP}"
fi
_exit_err "Source ${source} is not readable. Skipping."
fi
Then checking host activity is passed and backup process running successful.
--------------------------------------------------------------------------------
Changed it to "$@" "$source" instead, to be consistent and use options
before source.

Type of source is checked later anyway and using
ls -p1 results in "dir/", which we should cleanup
with "sed 's;/$;;' again, which is ugly.

The interval definition section was down to just before the
maximum backup check. This makes the code more friendly to
automatic interval selection. Auto interval selection needs to
have ddir defined first and it is best if it is done after
delete_incomplete. This change accomplishes that while still
placing it before the maximum backup check which needs to know
the interval.
so all incomplete backups are deleted, not just the ones with
the particular interval that the user specified.
The advantage of this is that those to-be-deleted incomplete
backups will not interfere with calculations required for
automatic interval selection.
Eight lines and two variables are removed which makes the code,
I think, easier to read.
The main motivation for this change, however, is that it makes
ccollect.sh more friendly to (future) auto interval selection.
The removed lines and variables assumed that the interval was
known prior to the start of the source loop. With auto interval
selection, the selected interval can be different for each
source.
If a source is not connectable, ccollect.sh issues a series of error
messages such as:
$ ccollect.sh "int 1" dummy
2009-06-25-21:04:14: ccollect 0.7.1: Beginning backup using interval int 1
[dummy] 2009-06-25-21:04:14: Beginning to backup
[dummy] ssh: connect to host Ha port 20: No route to host
[dummy] rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
[dummy] rsync error: unexplained error (code 255) at io.c(600) [receiver=3.0.5]
[dummy] 2009-06-25-21:04:17: Error: source Ha:/tmp is not readable. Skipping.
2009-06-25-21:04:17: Finished
If you expect the source to be up, you want to see these messages.
However, for a notebook computer or other portable machine, it may be
normal for it to be disconnected. If quiet_if_down is specified for
that source, then the ssh and rsync errors are suppressed and the
"Error:" prefix is removed from the "skipping" message:
$ ccollect.sh "int 1" dummy
2009-06-25-21:03:33: ccollect 0.7.1: Beginning backup using interval int 1
[dummy] 2009-06-25-21:03:34: Beginning to backup
[dummy] 2009-06-25-21:03:37: Source Ha:/tmp is not readable. Skipping.
2009-06-25-21:03:37: Finished
I considered the alternative implementation of adding the logic to
ccollect_analyse_logs.sh to enable it to separate rsync messages
generated the initial connection test from messages generated by
rsync used for an actual backup data transfer. Adding this approach
to ccollect.sh appeared much simpler.
By default, ccollect.sh sorts backup directories based on last change
time (ctime). This adds the option to sort based on modification
time (mtime).
I have updated doc/ccollect.text but it needs some work to simplify
and explain the issue.
After rsync, the destination directory's mtime reflects the
modification time of its immediate contents. This patch overrides
that and sets the mtime to the time that the backup finished.
With this patch, the age of a backup can be assessed by looking at
its mtime. The advantages of this are (1) that mtime can be
preserved, via cp -a or rsync -a, when copying a backup repository
to a new hard disk or a new machine and (2) that incorrect mtimes,
such as might happen after a user meddles with his backup
repository, can be, via touch, corrected. The disadvantage is that
mtime for the immediate contents of the destination directory is
lost.
User may optionally create a file rsync_failure_codes with a
newline-separated list of rsync return codes that are to be
regarded as complete failure.
If rsync exits with such a code, then the backup will be marked
for deletion during the next ccollect run (if delete_incomplete).
I added documentation for this feature in doc/ccollect.text
In my experience (yours may differ), two rsync exit codes that
belong in this file are 12 and 255. I have seen 12 result from
ssh errors and 255 result from a kernel module conflict. In both
cases, the resulting backups were empty. Without the
rsync_failure_codes option, such errors cause good backups to be
deleted, as per c_interval, leaving behind the new empty backups.
In the long run, we may want a different and more comprehensive
method for analyzing rsync errors. In the short run, I find this
option necessary.
