每天增量備份 SVN 儲存庫？（作業系統 = UNIX）

問題的第一部分如何進行 SVN 儲存庫的增量備份？執行此操作的命令是什麼……以及如何自動執行此操作（OS + UNIX）

如果您想自己做，請查看“svnlook youngest”和“svnadmin dump –incremental -r $ {STARTREV}: $ {ENDREV}”命令。

我在腳本下方粘貼了用於對我的 SVN 儲存庫進行完整和增量轉儲的腳本，它們將上次備份的修訂版和日期儲存在 /home/svn/var 的子目錄中。首先進行完整轉儲，然後根據需要進行盡可能多的增量轉儲。

完整的 SVN 轉儲腳本：

#!/bin/sh

# Full dump of all subversion repositories

# make sure to get the subversion environment variables
. /etc/profile.d/subversion.sh

# path to subversion binaries
SVN_BINPATH=${SVN_HOME}/bin

# path to parent of all repositories to be dumped
SVN_REPPATH=/opt/svn/repositories

# destination directory for backup files
DUMP_DIR=/backup/svn

# status directory
SVN_VAR=/home/svn/var

DATETIME=`date +%Y%m%d`

for rep in ${SVN_REPPATH}/*;
do
 TSTAMP=`date +%s`
 CURR_REV=`${SVN_BINPATH}/svnlook youngest ${rep}`
 REP_BASE=`basename $rep`

 echo "**********************************************************"
 echo "`date --rfc-2822`  - Full back up - ${rep} : "
 echo "     current revision ${CURR_REV}"
 echo

 DUMPFILE=${DUMP_DIR}/${REP_BASE}-${DATETIME}.dmp
 ${SVN_BINPATH}/svnadmin --quiet dump $rep > ${DUMPFILE}
 echo ${TSTAMP} > ${SVN_VAR}/status/dates/${REP_BASE}.dt
 echo ${CURR_REV} > ${SVN_VAR}/status/revisions/${REP_BASE}.rev
 bzip2 --compress --best ${DUMPFILE}
done

echo
echo `ls -hl ${DUMP_DIR}/*.bz2`

增量 SVN 轉儲腳本：

#!/bin/sh

# Incremental dump of all subversion repositories

# make sure to get the subversion environment variables
. /etc/profile.d/subversion.sh

# path to subversion binaries
SVN_BINPATH=${SVN_HOME}/bin

# path to parent of all repositories to be dumped
SVN_REPPATH=/opt/svn/repositories

# destination directory for backup files
DUMP_DIR=/backup/svn

# status directory
SVN_VAR=/home/svn/var

DATETIME=`date +%Y%m%d`

for rep in ${SVN_REPPATH}/*;
do
 TSTAMP=`date +%s`
 CURR_REV=`${SVN_BINPATH}/svnlook youngest ${rep}`
 REP_BASE=`basename $rep`

 if [ -e ${SVN_VAR}/status/dates/${REP_BASE}.dt ] ; then
   REP_LAST_BK_TSTAMP=`cat ${SVN_VAR}/status/dates/${REP_BASE}.dt`
   REP_LAST_BK_REV=`cat ${SVN_VAR}/status/revisions/${REP_BASE}.rev`
 else
   REP_LAST_BK_TSTAMP=0
   REP_LAST_BK_REV=0
 fi

 if [ ${CURR_REV} -gt ${REP_LAST_BK_REV} ] ; then
   echo "**********************************************************"
   echo "`date --rfc-2822`  - Incremental back up ${rep} : "
   echo "     oldest revision ${REP_LAST_BK_REV} - newest revision ${CURR_REV}"
   echo

   DUMPFILE=${DUMP_DIR}/${REP_BASE}-${DATETIME}-${REP_LAST_BK_REV}-${CURR_REV}.dmp
   ${SVN_BINPATH}/svnadmin --quiet dump $rep --incremental -r${REP_LAST_BK_REV}:${CURR_REV}> ${DUMPFILE}
   echo ${TSTAMP} > ${SVN_VAR}/status/dates/${REP_BASE}.dt
   echo ${CURR_REV} > ${SVN_VAR}/status/revisions/${REP_BASE}.rev
   bzip2 --compress --best ${DUMPFILE}
 fi
done

echo
echo `ls -hl ${DUMP_DIR}/*.bz2`

希望這可以幫助。
