Last change on this file since 1315 was 1315, checked in by bruno, 12 years ago

Log files are now consistent: mondoarchive.log for mondoarchive (containing also mindi.log) and mondorestore.log for mondorestore (copied from /tmp (ram) to /var/log (disk) at the end of the restore)
One include has been created for each bianry containing only that declaration ofr the moment, but which will be extended to include all local definitions (ps_* e.g.)
Doc updated accordingly
LOGFILE in restore process is now passed in the environment and not duplicated anymore
LogIt? is not redifined either
LOGFILE should be put in environment by mondoarchive for mindi's usage but that's a step left for later.

21.TH mondoarchive 8 "DDD" "Mondo Rescue VVV-rRRR"
22
23.SH NAME
24mondoarchive \- a backup / disaster\-recovery tool.
25
26.SH SYNOPSIS
27.B mondoarchive -O
28[
29.I options
30] : backup your PC
31.br
32.B mondoarchive -V
33[
34.I options
35] : verify your backup
36
37.SH DESCRIPTION
38.PP
39.I mondoarchive
40backs up a subset of your files, your entire filesystem, or even images of
41non-Linux filesystems to CD's, tape, ISO images or an NFS mount. In the event of
42catastrophic data loss, you will be able to restore everything, taking a PC from
43bare metal to its original state if necessary.
44
45.pp
46With
47.BR \-O ,
48it backs up your filesystem to CD, tape, ISO images or NFS share. Boot floppies
49or a special boot CD will be created to allow you to restore from bare metal if
50necessary.
51
52.pp
53With
54.BR \-V ,
55it verifies the backup against the live filesystem. This option may be used in
56combination with
57.BR \-O
58to verify a backup after its creation, or on its own to see how much the live
59filesystem has changed since the backup was made.
60
61.pp
62Call mondoarchive
63.BR without
64.BR flags
65to make it auto-detect as many settings as possible, ask you politely for the
66rest, and then backup and verify your OS or a subset thereof.
67
68.pp
69To restore data, either run
70.I mondorestore
71from the command line or boot from the emergency CD/floppies generated during
72the backup process. The latter will come in handy if a gremlin wipes your hard
73disk.
74
75.SH BACKUP MEDIA
76.TP 13
77You must specify one of the following:-
78
79.TP
80.BI "-c " speed
81Use CD-R drive as backup device and its (write-once) disks as backup media.
82
83.TP
84.BI "-w " speed
85Use CD-RW drive as backup device and its (write/rewrite) disks as backup media.
86Mondo will wipe media before writing to them.
87
88.TP
89.BI "-r "
90Use DVD drive as backup device and its disks as backup media. Growisofs decides
91on the best speed for your drive. Note that calling mondoarchive
92.B using sudo when writing to DVDs will fail
93because growisofs does not support this - see the growisofs manpage for
94details.
95
96.TP
97.BI "-C " speed
98Use CD-R drive as a streaming device, almost like a tape streamer. Use
99write-once disks as backup media.
100.B Experimental.
101
102.TP
103.BI "-p " prefix
104Use
105.B prefix
106to generate the name of your ISO images.
107By default, mondoarchive names images mondorescue-1.iso, mondorescue-2.iso, ...
108Using
109.B -p machine
110will name your images machine-1.iso, machine-2.iso, ...
111
112.TP
113.BI "-i "
114Use ISO files (CD images) as backup media. This is good for backing up your
115system to a spare hard drive. The
116.B -n
117switch is a wiser choice if you plan to restore from a remote filesystem.
118
119.TP
120.BI "-n " mount
121Use files residing on NFS partition as backup media.
122.I mount
123is the remote mount-point, e.g. '192.168.1.3:/home/nfs'
124for my file server. Please mount it before backing up/verifying.
125
126.TP
127.BI "-t "
128Use tape streamer as backup device and its tapes as backup media.
129
130.TP
131.BI "-u "
132Use a generic streaming device as backup device. Use this if you want to write
133your backup to a device that is not directly support by mondoarchive. This will
134send the data directly to a raw device.
135.B For experienced users only.
136
137.SH MAJOR OPTIONS
138.TP 13
139.BI "-D "
140Make a differential backup: examine the filesystem and find which files have
141changed since the last full backup was carried out. Backup only those files.
142
143.TP
144.BI "-E " "\*(lqpath ...\*(rq"
145Exclude path(s) from backup. The paths should be separated with a whitespace.
146Note that mondo automatically excludes removable media (/mnt/floppy,
147/mnt/cdrom, /proc, /sys, /tmp). For example, if you are backing up to an NFS mount but you
148do not want to include the contents of the mount in a backup, exclude your
149local mount-point with this switch. It will also work with partitions, e.g.
150/dev/sdd4 if you have a peculiar SCSI zip drive which insists on showing up in
151the mountlist. NB: If you exclude /dev/sdd4 then the /dev entry itself will
152still be backed up, even though the mountlist entry will be suppressed.
153N.B.: If you specify a directory with a final / its content will be archived so it won't do what you expect.
154
155.TP
156.BI "-I " "\*(lqpath ...\*(rq"
157Include paths(s) in backup. The default backup path is \*(lq/\*(rq but you may
158specify alternatives, e.g. -I \*(lq/home /etc\*(rq to override that.
159
160.TP
161.BI "-J " "file"
162Specify an explicit list of files and directories to include in a plain text file, one item
163(file or directory) per line. Beware that directories placed in that file are not managed recursively contrary to what is done with the -I option.
164
165.TP
166.BI "-N"
167Exclude all mounted network filesystems. This currently means NFS, SMB, Coda, MVFS, AFS
168and Netware. In other words, only backup the local hard disk(s).
169
170.TP
171.BI "-d " "dev|dir"
172Specify the backup device (CD/tape) or directory (NFS/ISO). For CD-R[W] drives,
173this is the SCSI node where the drive may be found, e.g. '0,1,0'. For tape
174users, this is the tape streamers /dev entry, e.g. '/dev/st0'. For ISO users,
175this is the directory where the ISO images are stored. For NFS users, this is
176the directory within the NFS mount where the backups are stored. The default
177for ISO and NFS is '/root/images/mondo'.
178
179.TP
180.BI "-g "
181GUI mode. Without this switch, the screen output of mondoarchive is suitable
182for processing by an 'expect' wrapper, enabling the user to backup nightly via
183a cron job. However, if you want to run this program with an attractive but
184non-cron-friendly interface then use '-g'.
185
186.TP
187.BI "-k " "path"
188Path of user's kernel. If you are a Debian or Gentoo user then specify
189.B -k FAILSAFE
190as your kernel. Otherwise, you will rarely need this option.
191
192.TP
193.BI "-m "
194Manual (not self-retracting) CD trays are often found on laptops. If you are
195a laptop user, your CD burner has BurnProof technology or you experience
196problems with mondo then please call mondoarchive with this switch.
197
198.TP
199.BI "-o "
200Use LILO as boot loader of boot floppy/CD instead of SYSLINUX/ISOLINUX. By
201default, SYSLINUX is used for floppies and ISOLINUX for CD's. Use LILO if you
202prefer to use that boot loader. NB: This does not affect which boot loader you
203use to boot your PC, merely the boot loader used by the CD's/floppies created
204by Mondo. Use ELILO instead which is mandatory for IA64 machines.
205
206.TP
207.BI "-s " "size"
208How much can each of your backup media hold? You may use 'm' and 'g' on the end
209of the number, e.g. '700m' for an extra-large CD-R. You no longer need to
210specify the size of your cartridges if you are backing up to tape.
211
212.TP
213.BI "-x " "'dev ...'"
214Specify non-Linux partitions which you want to backup, e.g. NTFS or BeOS.
215
216
217.SH MINOR OPTIONS
218.TP 13
219.BI "-[0-9] "
220Specify the compression level. Default is 3. No compression is 0.
221
222.TP
223.BI "-A " "command"
224This command will be called after each CD/NFS/ISO file is written. It is useful
225if you want to do something with an ISO after creating it, e.g. write it to a
226CD burner using a non-standard command.
227.B -A
228understands two tokens - _ISO_ and _CD#_ - which will be translated into the
229ISO's filename and its index number (1, 2, ...) respectively. So, you could use
230.I -A 'foobackup _ISO_; rm -f _ISO_'
231to feed each ISO to some magical new backup tool.
232
233.TP
234.BI "-B " "command"
235This command will be called before each CD/NFS/ISO file is written. See
236.B -A
237for more information.
238
239.TP
240.BI "-F "
241Do not offer to write boot+data floppy disk images to 3.5-inch floppy disks.
242The images will remain in /root/images/mindi until your next backup run,
243however.
244
245.TP
246.BI "-H "
247When you boot from the tape/CD, your hard drive will be wiped and the archives
248will be restored. Your decision to boot from the tape/CD will be taken as
249consent. No further permission will be sought.
250.B Use with caution.
251
252.TP
253.BI "-L "
254Use lzo, a fast compression engine, instead of bzip2. You may find lzo on
255Mondo's website or via FreshMeat. WARNING! Some versions of LZO are unstable.
256
257.TP
258.BI "-G "
259Use gzip, the standard and quicker Linux compression engine, instead of bzip2.
260
261.TP
262.BI "-R "
263EXPERIMENTAL. Do not use in mission-critical environments. Star is an alternative to afio. Mondo now supports POSIX ACLs and extended attributes, so -R is essentially redundant for now.
264
265.TP
266.BI "-P " "tarball"
267Post-nuke tarball. If you boot into Nuke Mode and everything is restored
268successfully then the
269.I post-nuke
270script will be sought and executed if found. This is useful for post-restore
271customization. It is assumed that the tarball (.tar.gz format) will contain not
272just the
273.I post-nuke
274script (or binary, or whatever it is) but also any files it requires.
275
276.TP
277.BI "-S " "path"
278Specify the full pathname of the scratchdir, the directory where ISO images are built before being
279archived. If you have plenty of RAM and want to use a ramdisk for scratch
280space, specify its path here.
281
282.TP
283.BI "-T " "path"
284Specify the full pathname of the tempdir, the directory where temporary files (other than ISO images
285being assembled) are stored. See
286.B -S
287
288.TP
289.BI "-W "
290Don't make your backup self-booting. This is a really bad idea, IMO. Don't do
291this unless you have really great boot disks in your hand and you are an anally
292retentive SOB who can't wait 2 minutes for Mindi to run in the background. If
293you use -W then you'd better know what the hell you're doing, okay?
294
295.TP
296.BI "-b "
297Specify the internal block size used by the tape drive. This is usually 32K but
298some drives just don't like that. They should but they don't. That's what
299happens when tape drive vendors don't talk to kernel driver writers. Try 512 or
30016384.
301
302.TP
303.BI "-e "
304Don't eject the CD or tape when backing up or restoring... unless cdrecord
305insists on it. If it does, well, tough. Sorry. :)
306
307.TP
308.BI "-f " "device"
309Specify the drive on which your Master Boot Record lives. Usually, this is
310discovered automatically.
311
312.TP
313.BI "-l " "GRUB|LILO|ELILO|RAW"
314Specify the boot loader. By default, your Master Boot Record is examined and
315the boot loader can usually be discovered. If you specify RAW then the MBR will
316be backed up and restored byte-for-byte without any analysis. It is likely that
317you will also need to specify the boot device with -f <dev>. ELILO is mandatory
318for IA64 machines.
319
320.TP
321.BI "-Q "
322Give more detailed information about the boot loader.
323
324.TP
325.BI "-K " "loglevel"
326Specify the loglevel. Use 99 for full debug. Standard debug level is 4.
327
328.TP
329.BI "-z "
330Use extended attributes and acl for each file and store them in the backup media. Use this option if you use SElinux e.g. but it will slow down backup and restore time of course.
331
332
333.SH DIAGNOSTICS
334Mondo generates one additional, and extremely important file:
335.BI /var/log/mondoarchive.log.
336When seeking technical support, attach this file to your email.
337
338
339
340.SH FILES
341.IR /var/log/mondoarchive.log
342This log contains important information required to analyse mondoarchive
343problem reports. Did I already said that it's highly recommended to send this file with
344support questions.
345
346.SH NOTES
347A link to Mondo's HTML-based manual (by Bruno Cornec, Mikael Hultgren, Cafeole, Randy Delphs,
348Stan Benoit, and Hugo Rabson) may be found at
