.SH SYNOPSIS

\fBrestic diff [flags] snapshotID snapshotID\fP
|

.SH DESCRIPTION
|
|
.PP
|
|
The "diff" command shows differences from the first to the second snapshot. The
|
|
first characters in each line display what has happened to a particular file or
|
|
directory:
|
|
|
|
.RS
|
|
.IP \(bu 2
|
|
+ The item was added
|
|
.IP \(bu 2
|
|
- The item was removed
|
|
.IP \(bu 2
|
|
U The metadata (access mode, timestamps, ...) for the item was updated
|
|
.IP \(bu 2
|
|
M The file's content was modified
|
|
.IP \(bu 2
|
|
T The type was changed, e.g. a file was made a symlink
|
|
.IP \(bu 2
|
|
? Bitrot detected: The file's content has changed but all metadata is the same
|
|
|
|
.RE
|
|
|
|
.PP
|
|
Metadata comparison will likely not work if a backup was created using the
|
|
\&'--ignore-inode' or '--ignore-ctime' option.
|
|
|
|
.PP
|
|
To only compare files in specific subfolders, you can use the
|
|
"snapshotID:subfolder" syntax, where "subfolder" is a path within the
|
|
snapshot.
|
|
|
|
|
|
