-rw-r–r– 1 root root 1024 Apr 2 20:00 /data/file1.txt
-rw-r–r– 1 root root 2048 Apr 2 20:00 /data/file2.txt
-rw-r–r– 1 root root 3072 Apr 2 20:00 /data/file3.txt

# 查看备份详细信息
# /usr/openv/netbackup/bin/admincmd/bpbackupinfo -backupid client1_1234567890

Backup ID: client1_1234567890
Policy: FULL_BACKUP
Schedule: Full
Client: client1
Start Time: 04/02/2026 20:00:00
End Time: 04/02/2026 20:30:00

5. 数据库恢复

数据库恢复是专门用于恢复数据库的操作，需要使用特定的恢复命令和工具。

5.1 Oracle数据库恢复

# 使用RMAN恢复Oracle数据库
# su – oracle
$ rman target /

RMAN> run {
> allocate channel ch1 type ‘SBT_TAPE’;
> set channel ch1 device type ‘SBT_TAPE’ parms ‘SBT_LIBRARY=/usr/openv/netbackup/bin/libobk.so64,ENV=(NB_ORA_CLIENT=dbserver1,NB_ORA_POLICY=ORACLE_BACKUP,NB_ORA_SCHED=Full)’;
> restore database;
> recover database;
> release channel ch1;
> }

Starting restore at 04/02/2026 11:00:00
using channel ORA_DISK_1
using channel ORA_SBT_TAPE_1

channel ORA_SBT_TAPE_1: starting datafile backup set restore
channel ORA_SBT_TAPE_1: specifying datafile(s) to restore from backup set
channel ORA_SBT_TAPE_1: restoring datafile 00001 to /oracle/oradata/ORCL/system01.dbf
channel ORA_SBT_TAPE_1: restoring datafile 00002 to /oracle/oradata/ORCL/sysaux01.dbf
channel ORA_SBT_TAPE_1: restoring datafile 00003 to /oracle/oradata/ORCL/undotbs01.dbf
channel ORA_SBT_TAPE_1: restoring datafile 00004 to /oracle/oradata/ORCL/users01.dbf
channel ORA_SBT_TAPE_1: restore complete, elapsed time: 00:15:30

Starting recover at 04/02/2026 11:15:30
using channel ORA_DISK_1
using channel ORA_SBT_TAPE_1

media recovery complete, elapsed time: 00:05:20

Finished recover at 04/02/2026 11:20:50

5.2 SQL Server数据库恢复

# 使用SQL Server Management Studio恢复数据库
# 或者使用T-SQL命令

RESTORE DATABASE [TestDB]
FROM DISK = N’\\nbu-server\backup\TestDB.bak’
WITH FILE = 1,
NOUNLOAD,
STATS = 5,
RECOVERY
GO

— 验证恢复结果
SELECT name, state_desc FROM sys.databases WHERE name = ‘TestDB’;

name state_desc
——————
TestDB ONLINE

6. 系统级恢复

系统级恢复用于恢复整个操作系统和应用程序，通常用于灾难恢复场景。

6.1 使用NetBackup Bare Metal Restore (BMR)

# 启动BMR恢复向导
# /usr/openv/netbackup/bin/bmrconfig -wizard

# 查看BMR客户端
# /usr/openv/netbackup/bin/admincmd/bmrc -listclients

Client Name: client1
Client OS: Linux
Client Type: BMR Client
Status: Ready

# 创建BMR恢复作业
# /usr/openv/netbackup/bin/admincmd/bmrc -createjob -client client1 -restoretype complete

Job ID: 12349

# 查看BMR恢复作业状态
# /usr/openv/netbackup/bin/admincmd/bmrc -queryjob -jobid 12349

Job ID: 12349
Status: Running
Progress: 50%

6.2 系统恢复验证

# 系统恢复完成后，启动系统
# 验证系统状态
# systemctl status

● client1

7. 恢复验证

恢复操作完成后，需要进行验证，确保数据恢复成功且完整。

7.1 文件恢复验证

# 验证文件存在性
# ls -la /data/
total 24
drwxr-xr-x 2 root root 4096 Apr 2 20:00 .
drwxr-xr-x 20 root root 4096 Apr 2 09:00 ..
-rw-r–r– 1 root root 1024 Apr 2 20:00 file1.txt
-rw-r–r– 1 root root 2048 Apr 2 20:00 file2.txt
-rw-r–r– 1 root root 3072 Apr 2 20:00 file3.txt

# 验证文件内容
# cat /data/file1.txt
This is a test file for backup and restore.

# 验证文件大小
# du -h /data/*
1.0K /data/file1.txt
2.0K /data/file2.txt
3.0K /data/file3.txt

7.2 数据库恢复验证

# 连接数据库
