b, data backup can reduce the time of a disaster. Cost recovery.
Second, the method of database backup:
● enterprise work, we need to back up the database, the most common method is to customize the script with regular tasks to achieve full standby database. Specific methods are as follows:
A, edit a custom script
VI /data/scripts/mysql-bak.sh
# / bin / the bash!
DATENOW = date +%Y%m%d
the DIR = / Data / Backup / dbbackup / "$ DATENOW"
DATETIME = date +%H%M
IF [-d "! the DIR $ "]
the then
mkdir -p / Data / Backup / dbbackup /" $ DATENOW "
Fi
/ usr / bin / the mysqldump -uroot--p 'password' -h 10.2.6.11 -A -B --single-transaction | gzip> "$ the DIR" /mysql$DATETIME.sql.gz
olddate = $ (DATE -d "-6 Days" "the Y +% m% D%")
CD / Data / Backup / dbbackup
for Folder in $ (LS -d / )
do
[Folder% {$ / } $ -LT-olddate] &

b, a new timer task:
30 2 * / bin / /data/scripts/mysql-bak.sh the bash> / dev / null 2>. 1 &
such 2:30 data per day will be a full database backup.
c, the results show:
[[email protected] dbbackup] LS #
20,190,724 20,190,725 20,190,726 20,190,727 20,190,728 20,190,729 20.19073 million
