The environment can +be copied regardless of whether it is currently in use. +No lockfile is created, since it gets recreated at need. + +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. + +.SH OPTIONS +.TP +.BR \-V +Write the library version number to the standard output, and exit. +.TP +.BR \-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. +.TP +.BR \-n +Open LDMB environment(s) which do not use subdirectories. + +.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. +.SH CAVEATS +This utility can trigger significant file size growth if run +in parallel with write transactions, because pages which they +free during copying cannot be reused until the copy is done. +.SH "SEE ALSO" +.BR mdb_stat (1) +.SH AUTHOR +Howard Chu of Symas Corporation <http://www.symas.com> |
