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.
