MDBX_COPY(1)		    General Commands Manual		  MDBX_COPY(1)

NAME
       mdbx_copy - MDBX	environment copy tool

SYNOPSIS
       mdbx_copy [-V] [-q] [-c]	[-n] src_path [dest_path]

DESCRIPTION
       The  mdbx_copy  utility copies an MDBX environment. The environment can
       be copied regardless of whether it is currently in use.	No lockfile is
       created,	since it gets recreated	at need.

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

OPTIONS
       -V     Write the	library	version	number to  the	standard  output,  and
	      exit.

       -q     Be quiet.

       -c     Compact  while  copying. Only current data pages will be copied;
	      freed or unused pages will be omitted from the copy. This	option
	      will  slow  down the backup process as it	is more	CPU-intensive.
	      Currently	it fails if the	environment has	suffered a page	leak.

       -n     Open MDBX	environment(s) which do	not use	subdirectories.	  This
	      is legacy	option.	For now	MDBX handles this automatically.

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.

CAVEATS
       This utility can	trigger	significant file size growth if	run in	paral-
       lel with	write transactions, because pages which	they free during copy-
       ing cannot be reused until the copy is done.
