.SH NAME
mdb_copy \- LMDB environment copy tool
.SH SYNOPSIS
.B mdb_copy
.I srcpath\ [dstpath]
.SH DESCRIPTION
The
.B mdb_copy
utility copies an LMDB environment. The environment can
be copied regardless of whether it is currently in use.

If
.I dstpath
is specified it must be the path of an empty directory
for storing the backup. Otherwise, the backup will be
written to stdout.

Note: currently, if the copy is interrupted a stale lock
will be left in the LMDB environment. This may be fixed
in a future release, but until then you must not
interrupt the copy process.

.SH DIAGNOSTICS
Exit status is zero if no errors occur.
Errors result in a non-zero exit status and
a diagnostic message being written to standard error.
