使用rclone备份mastodon数据

服务器有时间限制 Orz，万一哪天忘记续费全部木大完蛋。还是早点做个备份好。毕竟上面写了蛮多东西也不想丢弃。（想起QQ上写好多说说，当年….. 啊黑历史之后看见写的简直无语凝噎，都是无病呻吟的一些什么鬼东西啊！😧

准备

安装好rclone

已经配置完mastodon ps：当然看着教程随便设置同步位置也可以的

编写备份脚本

注意：这是源代码模式安装Mastodon后的执行备份脚本，因为最近迁移至Docker-Arm64，所以重新写了下Docker下的备份脚本，在下面。

编辑backup.sh

1

sudo nano /opt/onedrive_thy/mastodon-backup/backup.sh

我直接放在Onedrive的mastodon备份目录下咯

写入下面这么多东西：

 1

11

#!/bin/bash

# Save this file at  /opt/onedrive_thy/mastodon-backup/backup.sh
# Set a cronjob:  0 19 * * * /bin/bash /opt/onedrive_thy/mastodon-backup/backup.sh > /opt/onedrive_thy/mastodon-backup/logs/backup.log 2>&1

#Get the relative path of the backup script
backup_script=$(dirname "$realpath $0")

#Loading the Config
source $backup_script/config.sh

#Clean up old db dump
#rm /home/mastodon/live/dbbackup-*

#Generating a database dump backup
su - mastodon -c "cd /home/mastodon/live && pg_dump -Fc mastodon_production > dbbackup-$(date +"%Y_%m_%d_%I_%M_%p").dump"

#Loading the rclone password
#export RCLONE_CONFIG_PASS=$rclone_config_pass

#Moving the database backup
rclone move /home/mastodon/live/dbbackup-* $rclone_config_name:$onedrive_folder_name/$backup_folder_name

#Copying important files
rclone copy /home/mastodon/live/.env.production $rclone_config_name:/$onedrive_folder_name/$backup_folder_name
rclone copy /var/lib/redis/dump.rdb $rclone_config_name:/$onedrive_folder_name/$backup_folder_name
#rclone copy /etc/elasticsearch/jvm.options $rclone_config_name:$onedrive_folder_name/$backup_folder_name
    
#Remove dump files
rm /home/mastodon/live/dbbackup-*

编写完成后使用Ctrl+X退出，按Y保存。

PS ：因为我没有开全文搜索引擎 elasticsearch所以注释掉咯
PSS ：每个人的路径不一样，自己找找呗 😆

编辑config.sh

1

sudo nano /opt/onedrive_thy/mastodon-backup/config.sh

写入以下内容：

1
2
3
4
5
6
7
8
9


#!/bin/bash

# Save this file at  /opt/onedrive_thy/mastodon-backup/config.sh
# Replace the values below with your onedrive config

rclone_config_name="thy_disk"
# rclone_config_pass="yourpassword"
onedrive_folder_name=Data/Linux/VPS/Backups/TencentCloud/mastodon-backup
backup_folder_name="$(date +"%Y_%m_%d_%I_%M_%p")"

编写完成后使用Ctrl+X退出，按Y保存。

脚本检查

全部编写完成后运行一次：

1

bash /opt/onedrive_thy/mastodon-backup/backup.sh > /opt/onedrive_thy/mastodon-backup/logs/backup.log 2>&1

这一步会卡一会儿执行程序，在执行完成后查询日志：

1

cat /opt/onedrive_thy/mastodon-backup/logs/backup.log

或者直接登录网页或者win上的Onedrive查看（这好方便！

配置定期备份

编写定时任务：

1

crontab -e

写入下面这一坨，以后每天的凌晨5点（5点不是凌晨了叭）自动执行备份任务：

1

0 5 * * * bash /opt/onedrive_thy/mastodon-backup/backup.sh > /opt/onedrive_thy/mastodon-backup/logs/backup.log 2>&1

编写完成后使用Ctrl+X退出，按Y保存。

Docker下的备份脚本 | 2022-02-18 update

首先要明确自己需要备份哪些内容

按照优先级如下分类

.env.production 文件
数据库备份
嘟文图片
站点图片
外站数据

rclone move ${mastodon_folder}/backup/${SQL_FILE} $rclone_config_name:$onedrive_folder_name/$backup_folder_name

rclone copy ${mastodon_folder}/redis/dump.rdb $rclone_config_name:/$onedrive_folder_name/$backup_folder_name

echo 'OK'
