Scripts for SVN backup and recovery, remote backup based on rsync, and logging

SVN server: 192.168.40.110

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
