.SH SYNOPSIS
|
|
.sp
|
|
borg [common options] diff <options> REPO_ARCHIVE1 ARCHIVE2 PATH
|
|
.SH DESCRIPTION
|
|
.sp
|
|
This command finds differences (file contents, user/group/mode) between archives.
|
|
.sp
|
|
A repository location and an archive name must be specified for REPO_ARCHIVE1.
|
|
ARCHIVE2 is just another archive name in same repository (no repository location
|
|
allowed).
|
|
.sp
|
|
For archives created with Borg 1.1 or newer diff automatically detects whether
|
|
the archives are created with the same chunker params. If so, only chunk IDs
|
|
are compared, which is very fast.
|
|
.sp
|
|
For archives prior to Borg 1.1 chunk contents are compared by default.
|
|
If you did not create the archives with different chunker params,
|
|
pass \fB\-\-same\-chunker\-params\fP\&.
|
|
Note that the chunker params changed from Borg 0.xx to 1.0.
|
|
.sp
|
|
See the output of the "borg help patterns" command for more help on exclude patterns.
