Amanda is very versatile but it can be a bitch to configure and is IMHO |
16 |
only really worth it for larger installations with at least more than |
17 |
one machine and preferably a backup server. But it can also use dump(1) |
18 |
internally. I didn't really follow the thread but it seems dump has a |
19 |
problem with busy file systems? I used amanda with dump on several |
20 |
machines for a few years and never had any so it should be fine for a |
21 |
desktop. |
22 |
One method I used for getting the image size down (but which is no good |
23 |
on a live system) was to use "dd if=/dev/zero of=dummy bs=1M" to quicky |
24 |
write a file of zeroes that would fill up all free blocks, then dd the |
25 |
whole partition through gzip that would just compress away the free |
26 |
blocks. Works fine for install images but only when the disk is not |
27 |
mounted r/w during imaging. |
