Linux – Make Duplicity list files to be backed up

backupbashduplicitylinuxrsync

When using --dry-run with rsync it can list the files that will be backed up. But when I with duplicity do

duplicity --dry-run --name pchome --encrypt-sign-key xxx --include $HOME/Desktop --exclude '**' $HOME file:///mnt/backup

it just gives the statistics.

Question

How can I get duplicity to list the changes (copy/dalete) it will preform?

Increase the verbosity of output. According to duplicity man:

       --verbosity level, -vlevel
          Specify output verbosity level (log level).  Named levels and corresponding values
          are 0 Error, 2 Warning, 4 Notice (default), 8 Info, 9 Debug (noisiest).
          level may also be
          a character: e, w, n, i, d
          a word: error, warning, notice, info, debug

          The options -v4, -vn and -vnotice are functionally equivalent, as are the
          mixed/upper-case versions -vN, -vNotice and -vNOTICE.

--verbosity info worked for me

Linux – Using rsync to maintain a copy of a directory with a name that changes

One approach would be to do it in two steps. 1st, rsync everything except the directory in question by using ignore patterns. 2nd, rsync just the directory using globbing in bash to get to the directory, like this:

rsync -av /usr/lib/mydata/bigdatadir*/ /mnt/usbvolume/bigdatadir/

Using a trailing slash on the source directory will effectively cause rsync to ignore the directory name, because it will be invoked on the contents of the directory rather than the directory itself. Of course, this globbing will be easiest if the directory is named with a constant prefix or suffix as in my example above. If it isn't, you could write a script to figure out the actual name of the directory, and do something more direct like this:

rsync -av /usr/lib/mydata/$BIGDATADIRNAME/ /mnt/usbvolume/bigdatadir/

In the end, your pseudo-code would be something like this:

Find $BIGDATADIRNAME
Rsync everything as you were before, but ignore $BIGDATADIRNAME
Rsync the contents of $BIGDATADIRNAME

Linux – rsync – Exclude files that are over a certain size

There is a max-size option:

--max-size=SIZE         don't transfer any file larger than SIZE

So:

# rsync -rv --max-size=1.5m root@tss01:/tmp/dm

Will send only files less than 1.5m.

Regarding sizes from man: The suffixes are as follows: "K" (or "KiB") is a kibibyte (1024), "M" (or "MiB") is a mebibyte (1024*1024), and "G" (or "GiB") is a gibibyte (1024*1024*1024). If you want the multiplier to be 1000 instead of 1024, use "KB", "MB", or "GB". (Note: lower-case is also accepted for all values.) Finally, if the suffix ends in either "+1" or "-1", the value will be offset by one byte in the indicated direction*
