tar backup on tape in linux

by admin

Typical use:

backup: tar -clpzvf /dev/st0 /dir1 /dir2 /dir3
compare: tar -dlpzvf /dev/st0 /dir1 /dir2 /dir3
restore: tar -xlpzvf /dev/st0 /dir1 /dir2 /dir3

For multiple tapes just add the -M option:

tar -clpMzvf /dev/st0 /dir1 /dir2 /dir3
tar -dlpMzvf /dev/st0 /dir1 /dir2 /dir3
tar -xlpMzvf /dev/st0 /dir1 /dir2 /dir3

Debian 7.6

by admin

Keep getting mail and error logs thats say:

PHP Deprecated: Comments starting with ‘#’ are deprecated in /etc/php5/cli/conf.d/ming.ini on line 1 in Unknown on line 0

Solution:

Edit the file /etc/php5/apache2/conf.d/ming.ini
remove the first line: “#” so its only contains: “extension=ming.so” and nothing more.

Perl problems – I guess

After I did a dist-upgrade last-night, I’ve had some big problems with the server.

I solved this problem by : export LC_ALL=en_US.UTF-8
