.SH NAME
|
|
borg-key-export \- Export the repository key for backup
|
|
.SH SYNOPSIS
|
|
.sp
|
|
borg [common options] key export [options] [REPOSITORY] [PATH]
|
|
.SH DESCRIPTION
|
|
.sp
|
|
If repository encryption is used, the repository is inaccessible
|
|
without the key. This command allows one to backup this essential key.
|
|
Note that the backup produced does not include the passphrase itself
|
|
(i.e. the exported key stays encrypted). In order to regain access to a
|
|
repository, one needs both the exported key and the original passphrase.
|
|
.sp
|
|
There are three backup formats. The normal backup format is suitable for
|
|
digital storage as a file. The \fB\-\-paper\fP backup format is optimized
|
|
for printing and typing in while importing, with per line checks to
|
|
reduce problems with manual input. The \fB\-\-qr\-html\fP creates a printable
|
|
HTML template with a QR code and a copy of the \fB\-\-paper\fP\-formatted key.
|
|
.sp
|
|
For repositories using keyfile encryption the key is saved locally
|
|
on the system that is capable of doing backups. To guard against loss
|
|
of this key, the key needs to be backed up independently of the main
|
|
data backup.
|
|
.sp
|
|
For repositories using the repokey encryption the key is saved in the
|
|
repository in the config file. A backup is thus not strictly needed,
|
|
but guards against the repository becoming inaccessible if the file
|
|
is damaged for some reason.
