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/docs/FAQ.html#statistics.
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
37
39 --begin-time time
40 Do not read statistics files older than time. By default, all
41 statistics files will be read. time should be in the same for‐
42 mat taken by --restore-as-of. (See TIME FORMATS in the rdiff-
43 backup man page for details.)
44
45 --end-time time
46 Like --begin-time but exclude statistics files later than time.
47
48 --minimum-ratio ratio
49 Print all directories contributing more than the given ratio to
50 the total. The default value is .05, or 5 percent.
51
52 --null-separator
53 Specify that the lines of the file_statistics file are separated
54 by nulls (\0). The default is to assume that newlines separate.
55 Use this switch if rdiff-backup was run with the --null-separa‐
56 tor when making the given repository.
57
58 --quiet
59 Suppress printing of the "Processing statistics from session..."
60 output lines.
61
62
64 When aggregating multiple statistics files, some directories above (but
65 close to) the minimum ratio may not be displayed. For this reason, you
66 may want to set the minimum-ratio lower than need.
