Create dump of mysql base:

# mysqldump -uDBUSER -pPASSWORD DBNAME > filename.sql

or
# mysqldump --user=username --password=password DBNAME > filename.sql

if you need to make dump of a few databases you can use parametr -B (or –databases):

mysqldump -uDBUSER -pPASSWORD -B DBNAME1 DBNAME2 > filename.sql

Make dump of the all Databases on host:
mysqldump -uDBUSER -pPASSWORD -A > filename.sql

If you need only dump structure of database (without data):

mysqldump -uDBUSER -pPASSWORD --no-data DBNAME > filename.sql

If you want to make limited by records mysqldump, next command especially for you (It was really cool command when I need dump and then move test copy of project with enormous mysql database):

mysqldump -uDBUSER -pPASSWORD --where="true limit 100" DBNAME > filename.sql

this command will dump your database with defined amount records in each table.

- install ncftp freebsd:

#cd /usr/ports/ftp/ncftp3 && make install clean
#rehash

create ftp config file:

#touch /home/config/ftp.conf

– add information about ftp-server to /home/config/ftp.conf:

host ftp.howtobsd.com
user ftpuser
pass ftpfassword

and finally wonderful command:

ncftpput -f /home/anton/ftp.conf /backups /backup/forupload/*

/home/anton/ftp.conf- is ftp-connection information
/backups – folder on ftp-server
/backup/forupload/* – all files from this folder upload to ftp server

I successfully use it for delayed uploadding backups (ftp remote backup)

1.First of all we are going to install port fsbackup:

#cd /usr/ports/sysutils/fsbackup && make install clean

this is create directory /usr/local/fsbackup/ with scripts and config files

2.Let’is go to explore scripts and configs:

cache/ - directory for temporary hash
cfg_example - config example a good described and should be intuitive understandable. Follow I give my working config.
create_backup.sh – script running backup. You have to add it in /etc/crontab for automatically backup.
fsbackup.pl – it is a general sript of fsbackup
scripts/fsrestore.sh – restore you data
scripts/mysql_backup.sh – create backup MySQL database
scripts/pgsql_backup.sh – create backup PostgreSQL database
scripts/sqlite_backup.sh – create backup SQLLite database
scripts/sysbackup.sh – store system configuration files and information about installed packages
scripts/sysrestore.sh – reinstall packages stored by sysbackup.sh

If you want use any from this scripts (for example mysql_backup.sh and sysbackup.sh), you have to define it in the create_backup.sh start script (put “1″):

backup_mysql=1
backup_pgsql=0
backup_sqlite=0
backup_sys=1

Don’t forget put in this scripts your data. For example for properly storing mysql you have to fill your data such as:
backup_mysqluser="backuper"
backup_mysqlpassword="54dD1f6y7wfM959fM"
backup_path="/backup/mysql"

3.You also can separate your backups. For example your need to store mail in the one place (ftp-server or directory) while www-dir in the other:
Create two different config files by analogy with cfg_example (mail.conf and www.conf) and define it in start scripts directory: config_files=”mail.conf www.conf” -> create_backup.sh

4.This is promised my working config that store virtual mail folders:

$cfg_backup_name = "howtobsd_mail";
$cfg_cache_dir = "/usr/local/fsbackup/cache";
$prog_md5sum = "md5sum -b";
$prog_tar = "/usr/bin/tar";
$prog_ssh = "/usr/local/bin/ssh -i /usr/local/fsbackup/backup.prv";
$prog_rm = "/bin/rm";
$prog_gzip = "/usr/bin/gzip";
$cfg_checksum = "timesize";
$cfg_backup_style = "backup";
$cfg_increment_level = 16;
$cfg_save_old_backup = 1;
#$cfg_type = "remote_ftp";
$cfg_type = "local";
$cfg_remote_host="x.x.x.x";
$cfg_remote_password="backuper";
$cfg_remote_login="backuper";
$cfg_remote_path="/storage/backup/mail";
$cfg_local_path = "/backup/mail";
$cfg_time_limit = 0;
$cfg_size_limit = 100000;
$cfg_maximum_archive_size = 0;
$cfg_root_path = "/";
$cfg_stopdir_prune=0;
$cfg_verbose = 2;

This config describe local type. I prefer use ncftp for uploading backups to remote server.
I use “backup style” (increment) with cfg_increment_level = 16 – it’s mean that every 16 backup will be full (other only incremental). So, approximate twice on the month it do a full backup.

5.If you want use ftp remote backup type change this strings:

$cfg_type = "remote_ftp";
$cfg_remote_host = "ftp.server.com";
$cfg_remote_login = "ftpuser";
$cfg_remote_path = "tmp";
$cfg_remote_password = "ftppassword";

Check rights on the remote folder.
Security. If it possible deny port 21 for all exept your servers IP. If you are paranoiac or level security for your data is so high – use pgp encryption or vpn .

6. Finally, when you have finished configure add running start script to /etc/crontab:
10 1 * * * root /usr/local/fsbackup/create_backup.sh | mail -s "howtobsd backup report" root
Storing starting at 1:10 and sends reports to mail.

I did RAID-1 on the FreeBSD 7.1-RELEASE with two identical HDD – WD15EARS (1,5Tb)
I think you can use any hhd on condition that firs device have to be smoller size than second.

in my case:
- FreeBSD detect it as ad10 and ad16
- System has been installed in ad10 (with standard boot loader)

Before starting you have to do this:
howtobsd#sysctl kern.geom.debugflags=16

next you can add you device where has installed your system (In my situation it is ad10)

howtobsd#gmirror label -v -b round-robin gm0 /dev/ad10
Metadata value stored on /dev/ad10.
Done.

and add kernels module gmirror:

howtobsd#echo geom_mirror_load="YES" >> /boot/loader.conf

I’d advice you to backup your current version of fstab before editing:

howtobsd#cp /etc/fstab /etc/fstab.backup

edit your fstab-file very carefully.
howtobsd#vim /etc/fstab

you have to change /dev/ad10xxx on /dev/mirror/gm0xxx – (very carefully! you mustn’t forget “/mirror“)

my fstab before:
# Device Mountpoint FStype Options Dump Pass#
/dev/ad10s1b none swap sw 0 0
/dev/ad10s1a / ufs rw 1 1
/dev/ad10s1d /tmp ufs rw 2 2
/dev/ad10s1e /usr ufs rw 2 2
/dev/ad10s1f /var ufs rw 2 2
/dev/ad10s1g /vol1 ufs rw 2 2
/dev/ad10s1h /vol2 ufs rw,userquota 2 2

my fstab after:
# Device Mountpoint FStype Options Dump Pass#
/dev/mirror/gm0s1b none swap sw 0 0
/dev/mirror/gm0s1a / ufs rw 1 1
/dev/mirror/gm0s1d /tmp ufs rw 2 2
/dev/mirror/gm0s1e /usr ufs rw 2 2
/dev/mirror/gm0s1f /var ufs rw 2 2
/dev/mirror/gm0s1g /vol1 ufs rw 2 2
/dev/mirror/gm0s1h /vol2 ufs rw,userquota 2 2

going to reboot

and finally add second hdd in raid massive:

howtobsd#gmirror insert gm0 /dev/ad16

at this moment system started background mirroring
you can check status of rebuilding:
howtobsd# gmirror status
Name Status Components
mirror/gm0 DEGRADED ad10
ad16 (0%)

or more verbose:

howtobsd# gmirror list
Geom name: gm0
State: DEGRADED

GenID: 0

State: SYNCHRONIZING

GenID: 0

Synchronization can go on a long time (in my case about 7 hours)

Congratulate! When synchronized obtain 100% you can cut off one of your hdd and try to boot system for checking efficiency of RAID1 massive.

Oh…at last…
If one of your HDDs out of order – replace defective HDD and give command:

howtobsd#gmirror forget gm0
howtobsd#gmirror insert gm0 /dev/ad16

SVN (Subversion) is a version control system – useful instrument for developers who works on large-scale project.

I should draw your attention: it isn’t full manual about svn – it is only minimum that should be enough for start.

Install svn from ports system:

$whereis subversion
subversion: /usr/ports/devel/subversion
$cd /usr/ports/devel/subversion
$make install clean

I hope this manipulation well-khown for you.
When install already we add a few line in rc.conf:

svnserve_enable="YES"
svnserve_flags="-d --listen-port=3690"
svnserve_data="/www/svnroot"
svnserve_user="svn"
svnserve_group="svn"

where /www/svnroot folder that will include yours repositories. Make it before start svn.
You should make also svn group and svn user with home root directory:

$pw user add svn -g svn -s /sbin/nologin -d /www/svnroot/

It’s all systems go:

$/usr/local/etc/rc.d/svnserve start
Starting svnserve.

It’s ok! Now creat the repository:

$svnadmin create /www/svnroot/http/

change owner for folders to svn

$chown -R svn:svn /www/svnroot/

You should edit config file to close the anonym access in repository:

vim /www/svnroothome/http/conf/svnserve.conf

uncomment the line

anon-access = none
auth-access = write
password-db = passwd

add to /www/svnroot/http/conf/passwd line like

user = password

and restart svn

$/usr/local/etc/rc.d/svnserve restart

Congratulate yourself! You have just installed subversion and created svn repository.
