SVN backup/recovery script

SVN backup/recovery script

The previous article introduced the configuration of svn (see). Here we have written two scripts for full backup and recovery of svn. Because it is full backup, we can make a scheduled task and execute it once a day. Keep data for several days.

1. Backup script:
#! /Bin/sh

# Description: SVN full backup of the project
# Author: Mr. chen

DAY = 5 # Backup files keep days
TIME = 'date + % Y % m % d % H % m'
SVNPATH = "/data/svn"
BAKDIR = "/data/svnbak"
BAKPATH =$ {BAKDIR}/$ {TIME}
BAKLOG =$ {BAKDIR}/bak_svn.log

CONIFIG_FILE = '/bin/ls-lh $ {SVNPATH} | grep-E "^-" | awk' {print $ NF }''
