Oracle nfs集中备份替代NBU

配置NFS

https://www.linuxprobe.com/basic-learning-12.html

ORACLE各节点挂载nfs

mount  -t nfs4 -o minorversion=1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport 10.24.12.35:/ /backup

crontab定时执行全库备份及归档备份

全库备份（一天执行一次）：

su - oracle -c "rman target / nocatalog log /tmp/rman_full.log append<<EOF
CONFIGURE RETENTION POLICY TO REDUNDANCY 7;
run
{
allocate channel c1 type disk;
allocate channel c2 type disk;
backup as compressed backupset database
format '/backup/xxx/full_%d_%T_%s_%p'
plus archivelog
format '/backup/xxx/arch_%d_%T_%s_%p';

backup current controlfile format '/backup/xxx/ctl_%d_%T_%s_%p';
backup spfile format '/backup/xxx/spfile_%d_%T_%s_%p';
crosscheck backup;
crosscheck archivelog all;
delete noprompt archivelog until time 'sysdate-3' device type disk;
delete noprompt obsolete device type disk;
}
EOF"

归档（1小时备份一次）：

#!/bin/bash
su - oracle -c "rman target / nocatalog log /tmp/rman_arch.log append << EOF

backup as compressed backupset archivelog all format '/backup/xxx/arch_%d_%T_%s_%p';

EOF"
