.TH "restic backup" "1" "Jan 2017" "generated by \fBrestic generate\fR" ""
.SH NAME
restic-diff - Show differences between two snapshots
.SH SYNOPSIS
\fBrestic diff [flags] snapshotID snapshotID\fP
.SH DESCRIPTION
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:
.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
.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.
