Ubuntu下設定Redmine備份

Ubuntu下設定Redmine備份

備份redmine資料夾

編輯用於備份/home/redmine/redmine資料夾的腳本:

touch /home/redmine/backup/backup.sh
chmod +x /home/redmine/backup/backup.sh
vim /home/redmine/backup/backup.sh

填入以下內容:

# backup the folder '/home/redmine/redmine/'
echo '' | sudo -S rsync -av --no-o --no-g --progress --delete --log-file=/home/redmine/backup/$(date +%Y%m%d-%H%M%S)backup.log /home/redmine/redmine /mnt/tmp/Temp/backup/dataBackup-$(date +%Y%m%d-%H%M%S)
date +%Y%m%d-%H%M%S >> /home/redmine/backup/backup_time.txt

備份的目的地為/mnt/tmp/Temp/backup/dataBackup-。

備份時的log會記錄於/home/redmine/backup/backup.log。

備份的時間點會寫入/home/redmine/backup/backup_time.txt。

備份redmine資料庫

在/home/redmine/backup.sh中加入以下內容:

# backup databases 'redmine'
PGPASSWORD=<your_db_passwd> /usr/bin/pg_dump -U postgres -h localhost -Fc --file=/home/redmine/backup/redmine.sqlc redmine
gzip -c /home/redmine/backup/redmine.sqlc > /home/redmine/backup/redmine_`date +%Y%m%d-%H%M%S`.sqlc.gz
sudo cp -r -f --no-preserve=mode,ownership /home/redmine/backup/*.gz /mnt/tmp/Temp/backup && rm -r /home/redmine/backup/*.gz

將redmine資料庫導出壓縮成.sqlc.gz檔，並備份到/mnt/tmp/Temp/backup。

設定備份時程

設定備份時程:

crontab -e

以上指令會開啟編輯器，填入以下內容後，儲存並退出:

0 2 * * * /home/redmine/backup/backup.sh >> /home/redmine/backup/backup.log 2>&1 #2am every day

還原redmine資料夾

編輯用於還原/home/redmine/redmine資料夾的腳本:

touch /home/redmine/backup/restore.sh
chmod +x /home/redmine/backup/restore.sh
vim /home/redmine/backup/restore.sh

填入以下內容:

echo '' | sudo -S rsync -av --no-o --no-g --progress --log-file=/home/redmine/backup/$(date +%Y%m%d-%H%M%S)restore.log `find /mnt/tmp/Temp/backup -maxdepth 2 -wholename "/mnt/tmp/Temp/backup/dataBackup*/redmine" -type d -exec stat -c '%n' {} \; | sort -nr  | awk 'NR==1,NR==1 {print $1}'` /home/redmine/
sudo chown -R redmine:redmine /home/redmine/redmine

表示將最近備份的redmine資料夾複製到/home/redmine路徑下，並修改其擁有者為redmine。

還原時的log會記錄於/home/redmine/backup/restore.log。

還原redmine資料庫

在/home/redmine/backup/restore.sh中加入以下內容:

echo "" | sudo -S cp -r -f --no-preserve=mode,ownership `find /mnt/tmp/Temp/backup -maxdepth 1 -name "*.gz" -type f -exec stat -c '%Y %n' {} \; | sort -nr | awk 'NR==1,NR==1 {print $2}'` .
gunzip *.gz
PGPASSWORD=<your_db_passwd> pg_restore -U postgres -h localhost -d redmine redmine*.sqlc #user is "postgres" for database "redmine", check database.yml!

從/mnt/tmp/Temp/backup複製最近備份的.gz檔，將它解壓後導入到redmine資料中。

註:在還原redmine資料庫前需先建立一個名為redmine的空的資料庫。進入psql後:

CREATE DATABASE redmine;

others

find last modified file:

https://unix.stackexchange.com/questions/240418/find-latest-files

find . -maxdepth 1 -name "*.gz" -type f -exec stat -c '%Y %n' {} \; | sort -nr | awk 'NR==1,NR==1 {print $2}'

find last modified folder:

find . -maxdepth 1 -name "dataBackup*" -type d -exec stat -c '%Y %n' {} \; | sort -nr | awk 'NR==1,NR==1 {print $2}'

find folder whose name is largest:

find /mnt/tmp/Temp/backup -maxdepth 2 -wholename "/mnt/tmp/Temp/backup/dataBackup*/redmine" -type d -exec stat -c '%n' {} \; | sort -nr  | awk 'NR==1,NR==1 {print $1}'
