=head2 Won't I run out of disk space? |
776 |
|
|
777 |
|
Of course you will... Snapshots and logfiles will eventually fill-up your disk. |
778 |
|
However, you can do two things to stop that: |
779 |
|
|
780 |
|
=head3 Clean snapshort older than x days |
781 |
|
|
782 |
|
You can add following command to your C<root> crontab: |
783 |
|
|
784 |
|
find /backup/isis_backup -type d -mindepth 3 -maxdepth 3 -mtime +11 -exec rm -Rf {} \; |
785 |
|
|
786 |
|
I assume that C</backup/isis_backup> is directory in which are your snapshots |
787 |
|
and that you don't want to keep snapshots older than 11 days (that's |
788 |
|
C<-mtime +11> part of command). |
789 |
|
|
790 |
|
=head3 Rotate your logs |
791 |
|
|
792 |
|
I will leave that to you. I relay on GNU/Debian's C<logrotate> to do it for me. |
793 |
|
|
794 |
|
=head2 What are I<YYYYMMDD.partial> directories? |
795 |
|
|
796 |
|
If there isn't I<latest> symlink in snapshot directory, it's preatty safe to |
797 |
|
assume that previous backup from that day failed. So, that directory will |
798 |
|
be renamed to I<YYYYMMDD.partial> and snapshot will be performed again, |
799 |
|
linking same files (other alternative would be to erase that dir and find |
800 |
|
second-oldest directory, but this seemed like more correct approach). |
801 |
|
|
802 |
|
=head2 I can't connect to any share |
803 |
|
|
804 |
|
Please verify that nmblookup (which is part of samba package) is in /bin or |
805 |
|
/usr/bin. Also verify that nmblookup returns IP address for your server |
806 |
|
using: |
807 |
|
|
808 |
|
$ nmblookup tvhouse |
809 |
|
querying tvhouse on 192.168.34.255 |
810 |
|
192.168.34.30 tvhouse<00> |
811 |
|
|
812 |
|
If you don't get any output, your samba might not listen to correct interface |
813 |
|
(see interfaces in smb.conf). |
814 |
|
|
815 |
|
=head2 Aren't backups boring? |
816 |
|
|
817 |
|
No! If you have subjects.txt in same directory as C<psinib.pl> you can get |
818 |
|
various funny subjects in your mail. They change over time as long as you |
819 |
|
ignore your backup. |
