12
14 rdiff-backup-statistics reads the matching statistics files in a backup
15 repository made by rdiff-backup and prints some summary statistics to
16 the screen. It does not alter the repository in any way.
17
18 The required argument is the pathname of the root of an rdiff-backup
19 repository. For instance, if you ran 'rdiff-backup in out', you could
20 later run 'rdiff-backup-statistics out'.
21
22 The output has two parts. The first is simply an average of the all
23 matching session_statistics files. The meaning of these fields is
24 explained in the FAQ included in the package, and also at
25 https://rdiff-backup.net/FAQ.html#what_do_the_various_fields_mean_in_the_session_statistics_and_directory_statistics_files
26
27 The second section lists some particularly significant files (including
28 directories). These files are either contain a lot of data, take up
29 increment space, or contain a lot of changed files. All the files that
30 are above the minimum ratio (default 5%) will be listed.
31
32 If a file or directory is listed, its contributions are subtracted from
33 its parent. That is why the percentage listed after a directory can be
34 larger than the percentage of its parent. Without this, the root
35 directory would always be the largest, and the output would be boring.
36
38 --begin-time time
39 Do not read statistics files older than time. By default, all
40 statistics files will be read. time should be in the same format
41 taken by --restore-as-of. (See TIME FORMATS in the rdiff-backup man
42 page for details.)
43
44 --end-time time
45 Like --begin-time but exclude statistics files later than time.
46
47 -h, --help
48 Output a short usage description and exit.
49
50 --minimum-ratio ratio
51 Print all directories contributing more than the given ratio to the
52 total. The default value is .05, or 5 percent.
53
54 --null-separator
55 Specify that the lines of the file_statistics file are separated by
56 nulls ('\0'). The default is to assume that newlines separate. Use
57 this switch if rdiff-backup was run with the --null-separator when
58 making the given repository.
59
60 --quiet
61 Suppress printing of the ‘Processing statistics from session...’
62 output lines.
63
64 -V, --version
65 Output full path to command and version then exit.
66
68 When aggregating multiple statistics files, some directories above (but
69 close to) the minimum ratio may not be displayed. For this reason, you
70 may want to set the minimum-ratio lower than need.
