2024年11月如何使用backup-manager工具备份Linux系统(2)

发布时间:

  ⑴# Specify the backup method(s that will be used.

  ⑵# tarball: takes a list of directories and builds the corresponding tarballs.

  ⑶# mysql: archives MySQL databases using mysqldump. To restore the database, you # need to use the same tool manually.

  ⑷export BM_ARCHIVE_METHOD=“tarball mysql”

  ⑸# Where to store the backups.

  ⑹export BM_REPOSITORY_ROOT=“/var/archives”

  ⑺# The following directive indicates backup-manager to name

  ⑻# the generated files after the directory that was backed up.

  ⑼export BM_TARBALL_NAMEFORMAT=“long”

  ⑽# Define the pression type for the generated files.

  ⑾export BM_TARBALL_FILETYPE=“tar.gz”

  ⑿# List the directories that you want to backup.

  ⒀export BM_TARBALL_DIRECTORIES=“/etc /home /var/log”

  ⒁# Exclude some subdirectories or file extensions.

  ⒂export BM_TARBALL_BLACKLIST=“/var/log/myotherapp.log *.mp *.mp”

  ⒃# List the database(s that you want to backup, separated by spaces.

  ⒄export BM_MYSQL_DATABASES=“mysql mybase wordpress dotclear phpbb”

  ⒅# MySQL username.

  ⒆export BM_MYSQL_ADMINLOGIN=“root”

  ⒇# MySQL password for username.

  ⒈export BM_MYSQL_ADMINPASS=“mypassword”

  ⒉# Add support for DROP statements (optional。

  ⒊export BM_MYSQL_SAFEDUMPS=“true”

  ⒋# The hostname or IP address where the database(s reside.

  ⒌export BM_MYSQL_HOST=“localhost”

  ⒍# Port where MySQL server is listening.

  ⒎export BM_MYSQL_PORT=“”

  ⒏# pression type (optional。

  ⒐export BM_MYSQL_FILETYPE=“gzip”

  ⒑# Do not archive remote hosts, but only localhost.

  ⒒BM_TARBALL_OVER_SSH=“false”

  ⒓# User aount for SSH upload.

  ⒔export BM_UPLOAD_SSH_USER=“root”

  ⒕# Absolute path of the user‘s private key for passwordless SSH login.

  ⒖export BM_UPLOAD_SSH_KEY=“/root/.ssh/id_rsa”

  ⒗# Remote hosts (make sure you have exported your public key to them:

  ⒘export BM_UPLOAD_SSH_HOSTS=“dev dev”

  ⒙# Remote destination for uploading backups. If it doesn’t exist,

  ⒚# this directory will be created automatically the first time

  ⒛# backup-manager runs.

  ①export BM_UPLOAD_SSH_DESTINATION=“/var/archives/backups/$HOSTNAME”

  ②要手动运行备份管理器,请输入以下命令。你也可以选择添加‘-v’标识以便一步一步详细检查运行过程。

  ③# backup-manager

  ④BM_TARBALL_DIRECTORIES列出的目录将作为tarball备份到BM_REPOSITORY_ROOT目录,然后通过SSH传输到BM_UPLOAD_SSH_DESTINATION指定的主机dev和dev。

  ⑤正如你在上面图片中看到的那样,备份管理器在运行的时候创建了一个名为/root/.back-manager_my.f的文件,MySQL密码通过BM_MYSQL_ADMINPASS指定。那样,mysqldump可以验证到MySQL服务器,而不必在命令行以明文格式接受密码,那样会有安全风险。

  ⑥通过cron运行备份管理器

  ⑦一旦决定哪一天是进行每周备份的最佳日子(最佳时间,你可以让cron来为你运行备份管理器。

  ⑧打开root的crontab文件(注意,你必须以root登录:

  ⑨# crontab -e

  ⑩假定你想要在星期天的上午:分运行备份管理器,那么就添加下面这行。

  Ⅰ**/usr/sbin/backup-manager 》/dev/null》&

  Ⅱ上面就是Linux使用backup-manager备份系统的方法介绍了,相对于其他的备份工具,backup-manager更加的简单易用,是系统备份的好帮手。
