Backup server: 192.168.40.162
Local backup on SVN server
1. Full-scale backup
# vim /data/shell/backup_svn.sh#!/bin/sh#path= $PATH:/usr/local/subversion/binexport path# Define time variables for file name suffix date=$ (date +%f) #定义SVN库目录变量SVN_DIR_docs =/data/repositories/docs svn_dir_tools=/data/repositories /tools #定义备份文件存放目录变量SVN_BAK_DIR =/data/bak/ #初始化版本号, the full library backup must start from the 0 version number echo ' 0 ' > /data/ svnnum/docs_svn_idecho ' 0 ' > /data/svnnum/tools_svn_id #取初始化版本号NUM_docs1 =$ (cat /data/svnnum/docs_svn_id) num_tools1=$ (cat /data/svnnum/tools_svn_id) #取当前最新的版本号NUM_docs2 =$ ( svnlook youngest $SVN _dir_docs) num_tools2=$ (svnlook youngest $SVN _dir_tools) # Backup user authentication and authorization file \cp /data/Repositories/{authz,passwd} /data/bak/. #开始备份 # To determine if the backup was successful and, if successful, The current latest version number is recorded in the temporary file for the next incremental backup using ALL_BACKUP_SVN () { svnadmin dump $SVN _dir_docs -r $ NUM_DOCS1: $NUM _docs2 --incremental > $SVN _bak_dir/docs_bak_$dateif [ $? -eq 0 ]; thenecho $NUM _docs2 > /data/svnnum/docs_svn_idelseecho "$ (date +%f) docs backup fail >> /tmp/svnback.logfisvnadmin dump $SVN _dir_tools -r $NUM _tools1: $NUM _tools2 --incremental > $SVN _bak_dir/tools_bak_$ dateif [ $? -eq 0 ];thenecho $NUM _tools2 > /data/svnnum/tools_svn_ idelseecho "$ (date +%f) tools backup fail ..." >> /tmp/svnback.logfi} all_backup_svn
2. Incremental backup
# vim /data/shell/day_backup_svn.sh#!/bin/bash#path= $PATH:/usr/local/subversion/binexport path# defining time variables for file name suffixes date=$ (date +%f) #定义SVN库目录变量SVN_DIR_docs =/data/repositories/docs svn_dir_tools=/data/ repositories/tools #定义备份文件存放目录变量SVN_BAK_DIR =/data/bak/ #取初始化版本号NUM_docs1 =$ (cat /data/svnnum/ docs_svn_id) num_tools1=$ (cat /data/svnnum/tools_svn_id) #取当前最新的版本号NUM_docs2 =$ (svnlook youngest $SVN _dir_docs) num_tools2=$ (svnlook youngest $SVN _dir_tools) #开始备份 # To determine if the backup was successful, The current latest version number is recorded in the temporary file for the next incremental backup using DAY_BACKUP_SVN () {if [ $NUM _docs1 -lt $NUM _docs2 ];then svnadmin dump $SVN _dir_docs -r $NUM _docs1: $NUM _docs2 --incremental > $SVN _bak_dir/docs_bak_$dateif [ $? -eq 0 ];thenecho $NUM _ docs2 > /data/svnnum/docs_svn_idelseecho "$ (date +%f) docs backup fail ..." >> /tmp/svnback.logfifiif [ $NUM _tools1 -lt $NUM _tools2 ];thensvnadmin dump $SVN _dir_tools -r $NUM _tools1: $NUM _tools2 --incremental > $SVN _bak_dir/tools_bak_$ dateif [ $? -eq 0 ];thenecho $NUM _tools2 > /data/svnnum/tools_svn_ idelseecho "$ (date +%f) tools backup fail ..." >> /tmp/ Svnback.logfifi}day_backup_svn
3. Add a Scheduled task
# crontab-e#start0 2 * * */usr/sbin/ntpdate time.nist.gov >/dev/null 2>&1# make a full backup every Sunday * * 0/data/she ll/backup_svn.sh &>/dev/null# Incremental Backup of SVN * * 1-6/data/shell/day_backup_svn.sh
4. Configure the Rsync server:
# rpm -qa rsync (If you install yum install rsync - Y) rsync-3.0.6-12.el6.x86_64# yum install xinetd -y Enable rsync# vim /etc/xinetd.d/ rsync # default: off# description: the rsync server is a good addition to an ftp server, as it # allows crc checksumming etc.service rsync{ disable = no flags = IPv6 Socket_type = stream wait = no user = root server = /usr/bin/rsync server_args = --daemon log_on_failure += userid}
Rsync configuration file Available # vim /etc/rsyncd.conf#rsync --daemon --config=/etc/rsyncd.conf# Global options strict modes =yes # whether to check permissions for password files port = 873# default port 873 log file = /var/log/rsyncd.log# Log Record file pid file = /var/run/rsyncd.pid# Where the ID of the running process is written [svn]path = /data/bak# here is the name of the authentication module, which needs to be specified on the client side max connections = 0# client Maximum number of connections, default 0 (No limit) uid = root# Specifies the uid gid = that the daemon should have when the module transfers files root# specifies that the gid ignore errors# that the daemon should have when the module transmits the file can ignore some unrelated IO errors read only = yes# no client can upload files, yes read-only write only = no# no client can download files, yes cannot download hosts allow = * # any host connection #hosts deny = 10.5.3.1# Disable the specified host connection auth users = root# authenticated user name, if not this line, indicates that it is anonymous secrets file = /etc/backserver.pas # specifying the authentication password file location
5. Provide the authentication file, and the permission must be 600
# Vim/etc/backserver.pas root:123456# chmod 600/etc/backserver.pas
6. Restart the service
#/etc/init.d/xinetd Restart
7. Synchronizing backups to 192.168.40.162
Provide the authentication file, and the permissions must be 600
# Vim/etc/backserver.pas 123456# chmod 600/etc/backserver.pas# mkdir-p/data/bak/svn# vim/home/bak/backup_svn.sh #!/b in/bash# Backup SVN warehouse/usr/bin/rsync-vzrtopg--progress--delete [email protected]::svn/data/bak/svn--password-file=/etc/ Backserver.pas Add Timer Task # crontab-e#start0 2 * * */usr/sbin/ntpdate time.nist.gov >/dev/null 2>&1# Backup svn35 01 * * */home/backup_svn.sh &>/dev/null#end
8. SVN Recovery test
# mkdir Docs # svnadmin Create Newrepos # svnadmin load Newrepos < docs_bak_mon# svnadmin load Newrepos < docs_bak_t UE # Svnadmin Load Newrepos < docs_bak_wed# svnadmin load Newrepos < docs_bak_thu# svnadmin load Newrepos < Docs_ bak_fri# svnadmin load Newrepos < Docs_bak_sun
