.SH NAME
.PP
restic-diff - Show differences between two snapshots


.SH SYNOPSIS
.PP
\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.


.SH EXIT STATUS
.PP
Exit status is 0 if the command was successful.
Exit status is 1 if there was any error.
Exit status is 10 if the repository does not exist.
Exit status is 11 if the repository is already locked.
Exit status is 12 if the password is incorrect.
