Linux环境下磁带机的直接备份操作Working with “mt” Commands: reading and writing to tape.The following assumes the tape device is “/dev/st0″STEP 1 ( rewind the tape)# mt -f /dev/st0 rewindSTEP 2 (check to see if you are at block 0)# mt -f /dev/st0 tellAt block 0.STEP 3 (Backup “tar compress” directories “one” and “two”)# tar -czf /dev/st0 one twoSTEP 4 (Check to see what block you are at)# mt -f /dev/st0 tellY ou should get something like block 2 at this point.STEP 5 (Rewind the tape)# mt -f /dev/st0 rewindSTEP 6 (List the files)# tar -tzf /dev/st0one/one/testtwo/STEP 7 (Restore directory “one” into directory “junk”). Note, you have to first rewind the tape, since the last operation moved ahead 2 blocks. Check this with “mt -f /dev/st0″.# cd junk# mt -f /dev/st0 rewind# mt -f /dev/st0 tellAt block 0.# tar -xzf /dev/st0 oneSTEP 8 (Next, take a look to see what block the tape is at)# mt -f /dev/st0 tellAt block 2.STEP 9 (Now backup directories three and four)# tar -czf /dev/st0 three fourAfter backing up the files, the tape should be past block 2. Check this.# mt -f /dev/st0 tellAt block 4.Currently the following exist:At block 1:one/one/testtwo/At block 2:three/three/sampleherefour/At block 4:(* This is empty *)A few notes. Y ou can set the blocking factor and a labelwith tar. For example:$ tar ?label=”temp label” ?create ?blocking-factor=128 ?file=/dev/st0 Notes But note if you try to read it with the default, incorrect blockingfactor, then, you will get the following error:$ tar -t ?file=/dev/st0tar: /dev/st0: Cannot read: Cannot allocate memorytar: At beginning of tape, quitting nowtar: Error is not recoverable: exiting nowHowever this is easily fixed with the correct blocking factor$ mt -f /dev/st0 rewind$ tar -t ?blocking-factor=128 ?file=/dev/st0temp labelNotesT ake advantage of the label command.$ MYCOMMENTS=”Big_important_tape”$ tar ?label=”$(date +%F)”+”${MYCOMMENTS}”Writing to tape on a remote 192.168.1.155 computer$ tar cvzf - ./tmp | ssh -l chirico 192.168.1.155 …(mt -f /dev/st0 rewind; dd of=/dev/st0 )‟Restoring the contents from tape on a remote computer$ ssh -l chirico 192.168.1.155 …(mt -f /dev/st0 rewind; dd if=/dev/st0 )‟|tar xzf - Getting data off of tape with dd command with odd blocking factor.

See the ARCserve 2000 documentation for moreinformation on how to use the software.Backing Up SnapshotsBacking up snapshots eliminates the possibility of files changing during the backup job.Snapshots always contain the data that existed when the snapshot was taken.NOTE: When backing up a snapshot, Dell recommends that you deselect the ActiveArchivesubdirectory that is contained within each snapshot. If you do not deselect this subdirectory, yourbackup software will back up all the snapshots on your system. This action creates multiplecopies of your data, which causes you to use more tapes than necessary.To back up a snapshot:1Use the PowerVault NAS Manager to create a snapshot.2Select the snapshot in your backup software.3Deselect the ActiveArchive subdirectory.4Back up the snapshot just as you would a standard file system.Limitations on Backing Up Snapshots•Y ou cannot do incremental or differential backups of snapshots.•Y ou cannot use GFS rotation schemes when backing up snapshots.Loc al Ba ck up1-91-10Local Ba ck up ww w .d e l l .c o m | s u p p o r t .d e l l .c o m •Y ou cannot schedule a backup of a snapshot.Y ou must do a manual backup of snapshot files because each snapshot file name is unique in that it includes the date and time (hour-minute-second) that the snapshot was taken.•When you restore a snapshot, you must redirect the restore to a location other than the original snapshot location. A restore to the original location will not be successful.。

ESXI上虚拟机连接磁带机备份操作步骤:
1.vsphere Client上，连接配置→高级设置→VMDirectPath配置→编辑,打开虚拟机直通配置
列表:
2.直通配置列表中，选择SAS 3G HBA卡：
3.确定后会提示直通配置需要重启主机后才生效，重启主机。

4.关闭虚拟机，在虚拟机右键打开编辑配置，添加PCI设备，并选择SAS 3G HBA卡:
5.开启虚拟机，查看设备管理器，此时会搜索到一个未知SCSI控制器设备，安装SAS 3G HBA
卡驱动，再安装磁带机驱动，测试备份还原成功。

BTW:在此配置时，留意好警告信息和提醒事项:
1.可能会导致主机无法正常引导：
2.牺牲部分功能及浪费资源:。

Linux 磁带机备份完全攻略/safe/752965.html一、确定数据备份策略首先必须确定在备份过程中操作哪些文件。

在商业环境中，这是非常困难的一个决定，而且会产生严重的影响。

如果备份了太多数据，会导致备份系统的成本过于庞大，会削减其他方面的开支。

如果没有备份足够的数据，那么重要的数据就可能会丢失。

备份整个系统非常简单(请确保不要备份NFS挂载的一些目录和诸如/proc/之类的特殊文件系统)，但是通常这样备份的内容都太多了。

如果整个系统盘上的数据都丢失了，那么在恢复任何数据之前，很可能不得不重新安装基本的操作系统。

将这些系统文件保存在备份磁带上不是毫无意义的。

因此，为了减少备份系统的成本(包括硬件、网络、系统负载和备份时间)，通常应该只备份重要的文件。

共享程序：可以在多个系统中使用的公共程序。

/usr/local或/opt目录常在多个系统之间共享，这些目录包含没有随操作系统提供的其他操作系统。

用户数据：包含所有用户数据和私人文件的用户主目录。

应用程序数据：在分布式计算环境中，应用程序的数据通常在多个系统之间共享。

例如，Web服务器群集通常需要共享相同的内容。

系统信息：系统信息包括账户信息(用户、组和密码)、邮件别名、主机列表等。

只有您才知道自己的数据保存在什么地方，在建立自己的备份系统之前，至少要好好想一想这个问题。

虽然我不可能列出需要备份的每一份数据，但可以提供一些指导，包括：重要的系统数据：不要忘记重要的系统数据，如/etc/目录中的文件，有时是/var/目录中的文件。

如果这些文件都是自动生成的，那么可能只需要在主系统上备份这些文件。

后来添加的软件：包括系统中安装的任何非原操作系统所提供的软件。

您可能已经将这些软件安装到/opt/或/usr/local/目录中了，这样可以简化这些软件的备份过程。

或者，您也可能将所有这些程序都安装到一个集中的文件服务器上，这样会使备份过程更加简单。

如果系统中安装了一些软件包，要确保保存这些已经安装好的包，并在备份过程中包含这些软件包。

BE备份硬盘至磁带机文件备份使用步骤BE备份硬盘至磁带机文件备份：一、新建设备池：打开BE软件如下界面如图：1设备栏选择“设备”项，如下图：2点击：“自动化介质库”点击：“HP2 ”右键，如下图： 3点击：“配置分区”项，如下图： 4单击每个新分区应从中开始的插槽，以便选择每个分区要包含的自动化介质库插槽。

无论您单击何处，都会插入一个分区分隔栏，其中列出分区中包含的插槽范围。

例如，如果您想在带有 10 个插槽的自动化介质库上创建两个 5 插槽分区，请单击插槽 1 和插槽 6。

在本例中，插槽 1-5 将包括在第一分区中，而插槽 6-10 将包括在第二分区中。

分区可以包含任意数目的自动化介质库插槽；但是，如果存在其他分区，则不能移动或删除第一个分区。

注意: 第一个插槽的编号可能为 1 或 0，具体取决于自动化介质库的配置。

如果自动化介质库使用从零开始编号的插槽配置，而您指定第一个分区从插槽 1 开始，则分区实用程序实际上会将插槽 0 用作分区 1 的第一个插槽，并相应地调整其他所有分区的起始插槽。

如下图： 5划区：如下图： 6点击：“是”分区就划分好了。

如果觉得这样分区不好，可以点击“删除分区”或“全部删除”来重新划分。

如下图：7设备池建完成。

二、介质集的创建点击：任务栏---选“介质集”项，如下图：8在“介质集”点右键属性，选新建介质集，如下图：9在名称栏中输入名称，如：Bebackup1 Bebackup2 两个介质集，如上图，点确认如下图：10设备池新建完成，接下来将介质与介质集关联。

如下图：11在导航栏上，单击介质--展开全部介质显示介质列表，选择要与某个介质集关联的介质。

将介质拖到介质集。

如下图：12全选托到介质集BEbackup1 查看如下图：13如上图，介质集已经关联。

注:上图创建了两个介质集,BEbackup1 BEbackup2 现把所磁带都关联到BEbackup2。

介质集可以创建多个,一个介质集可放一带或多带。
