manual save of a linux host

Experts,

I'd like to backup a linux host including all the vfstab mounts like /oracle/data, oracle/log ...

save -s /

backs up all under but no mounts from the vfstab

save -s -x /

will attempt to follow e.g. /proc/kmsg and hang

Do I have to explicitly list all the directories that I wish to backup, or is there an easy way to accomplish it?

Many thanks

Christian

Chris,

     Since the mount points are NFS shares they will have to be listed explicitly as a saveset for it to be backed up. All picks up only the mount points that are defined in the fstab.

Nope, manual save need the saveset name be provided explicitly. If this is going to be a part of a script you could update the name of the mount point from the fstab before running backups.

But why do you want to run the backup manually rather than scheduling them which is a better option.

Hi crazyrov,

it's not about NFS shares. See below

[entw] [root@lhXXX ~]# df -h

Filesystem                            Size  Used Avail Use% Mounted on

/dev/mapper/vgroot-lvroot            2.0G  366M  1.6G  20% /

tmpfs                                939M    0  939M  0% /dev/shm

/dev/mapper/vgroot-lvappl            248M  11M  226M  5% /appl

/dev/sda1                            248M  99M  137M  42% /boot

/dev/mapper/vgroot-lvhome            1008M  34M  923M  4% /home

/dev/mapper/vgroot-lvopt              504M  17M  462M  4% /opt

/dev/mapper/vgroot-lvtmp              4.0G  210M  3.6G  6% /tmp

/dev/mapper/vgroot-lvusr              2.0G  1.1G  883M  54% /usr

/dev/mapper/vgroot-lvvar            1008M  405M  553M  43% /var

/dev/mapper/vgroot-lvlog            1008M  84M  874M  9% /var/log

/dev/mapper/vgtech-lvbmc            1008M  301M  657M  32% /opt/bmc

/dev/mapper/vgtech-lvrch              504M  17M  462M  4% /opt/rch

/dev/mapper/vgtech-lvrear            2.5G  117M  2.3G  5% /opt/rch/rear

/dev/mapper/vgtech-lvzexec            248M  11M  226M  5% /opt/zexec

/dev/mapper/vgdata01-lvmysql        1008M  124M  833M  13% /appl/mysql

/dev/mapper/vgdata01-lvmytest        9.9G  904M  8.5G  10% /appl/mysql/var/data/test

/dev/mapper/vgdata01-lvmytestbkp      9.9G  946M  8.5G  10% /appl/mysql/var/backup/test

I'd like to manually backup of all the mounted Filesystems. The use of save -x will stumble over the special files like /proc/kmsg.

I want to avoid to create an input file each time the system should be backed up. I'd rather specify save set "all" and let NetWorker do the job. But manual backups does not offer to specify save set "all", does it?

Thanks

Christian

Well, you could create an adhoc backup group containing this client. Run start the group before you do the changes.

It's simple, prior to performing an upgrade or a change in system or software settings I'd like to run a manual backup. That's only an additional backup to the ones scheduled at the NetWorker server.

You can:

- run backup for that client only, eg. savegrp -l full -c , or

- you could run backup from client, but of course you must specify each fs

You can get list from savefs, for example run savefs -s -vpn and parse list of file systems as such.

I'm quite sure that last backup prior to change in system or software setting should be enough without any extra backup unless you are changing settings every 5 minutes.
