I've been in the same boat the last week, and have investigated |
7 |
a number of options, and seem to be settling on app-backup/dar. |
8 |
It compresses; does incrementals; creates split archives of any |
9 |
given size; can keep an online catalog of offline data; and can |
10 |
even encrypt. |
11 |
|
12 |
Sample run: |
13 |
|
14 |
dar -c /backups/root-$(date -I)-full ! what to write |
15 |
-R / ! what to dump (root) |
16 |
-M ! don't span filesystems |
17 |
-s 700M ! Write CD-size files? |
18 |
-y ! compress... |
19 |
-Z '*.gz' -Z '*.tgz' -Z '*.zip' ! ...but don't compress these |
20 |
-P usr -P tmp -P var/cache ! Exclude these directories |
21 |
-D ! (write them as empty dirs) |
22 |
|
23 |
This assumes that /backups is a separate filesystem. Many of |
24 |
those default options can and should be put in /etc/darrc. |
25 |
|
26 |
The above command will write /backups/root-<date>-full.1.dar, .2.dar, |
27 |
as many as it needs. It's then up to you to write those to CD/DVD. |
28 |
|
29 |
Note that mkisofs doesn't yet grok >2G files. At this writing, |
30 |
the cdrtools-devel version claims to... but I'm not interested |
31 |
in verifying that claim :-). So you can't really do -s 4608M |
32 |
or whatever the size is for a DVD. |

Lots more info, including very thorough documentation and tutorials, |
