Typical usage would be: - tdbbackup *.tdb - when Samba shuts down cleanly, which will make a backup of all the local databases - to *.bak files. Then on Samba startup you would use: - tdbbackup -v *.tdb - and this will check the databases for corruption and if corruption is detected then - the backup will be restored. - - You may also like to do a backup on a regular basis while Samba is - running, perhaps using cron. - - The reason this program is needed is to cope with power failures - while Samba is running. A power failure could lead to database - corruption and Samba will then not start correctly. - - Note that many of the databases in Samba are transient and thus - don't need to be backed up, so you can optimise the above a little - by only running the backup on the critical databases. - - */ - -#ifdef STANDALONE -#if HAVE_CONFIG_H -#include <config.h> -#endif - -#include <errno.h> -#include <stdlib.h> -#include <stdio.h> -#include <fcntl.h> -#include <unistd.h> -#include <string.h> -#include <fcntl.h> -#include <time.h> -#include <sys/mman.h> -#include <sys/stat.h> -#include <sys/time.h> -#include <ctype.h> -#include <signal.h> - -#else - -#include "includes.h" - -#endif - -#include "tdb.h" -#include "tdbback.h" - -/* - see if one file is newer than another -*/ -static int file_newer(const char *fname1, const char *fname2) -{ - struct stat st1, st2; - if (stat(fname1, &st1) != 0) { - return 0; - } - if (stat(fname2, &st2) != 0) { - return 1; - } - return (st1.st_mtime > st2.st_mtime); -} - -static void usage(void) -{ - printf("Usage: tdbbackup [options] <fname...>\n\n"); - printf(" -h this help message\n"); - printf(" -s suffix set the backup suffix\n"); - printf(" -v verify mode (restore if corrupt)\n"); -} - - - int main(int argc, char *argv[]) -{ - int i; - int ret = 0; - int c; - int verify = 0; - const char *suffix = ".bak"; - extern int optind; - extern char *optarg; - - while ((c = getopt(argc, argv, "vhs:")) != -1) { - switch (c) { - case 'h': - usage(); - exit(0); - case 'v': - verify = 1; - break; - case 's': - suffix = optarg; - break; - } - } - - argc -= optind; - argv += optind; - - if (argc < 1) { - usage(); - exit(1); - } - - for (i=0; i<argc; i++) { - const char *fname = argv[i]; - char *bak_name; - - bak_name = add_suffix(fname, suffix); - - if (verify) { - if (verify_tdb(fname, bak_name) != 0) { - ret = 1; - } - } else { - if (file_newer(fname, bak_name) && - backup_tdb(fname, bak_name) != 0) { - ret = 1; - } - } - - free(bak_name); - } - - return ret; -} |
