Veeam Backup Replication Setup

As we know Veeam Trending two words enterprise backup tool for VM infra.

Going forward couple of posts will be posted on this tool

I have created a LAB with ESXi host and couple of other servers on my new LAB..

Enjoy. ...

Primary installation :

By registering you business mail id at Veeam you can download temporary licence of Veeam products for 30 Days.

If you are planning a dedicated service account that should be in Local Administrator group of Veeam Backup server.

You can't install Veeam on A domain controller and any other co existing application which uses SQL and IIS.

If you want integrate vCenter , you must have vCenter Login Credentials to  Add the vCenter to Veeam Backup server.

if you want recover Host backup at file system level , you must have host login or host domain account login details.

Hope this help............:)

Database Backups Oracle Recovery through RMAN --------------------DB Backups Part 2

Here is the recovery from RMAN Side. it is as simple as from RMAN side now the big deal how we are going to work with this tool using backup software's, as we all know any integrated backup works through a API to backup in a flexible method.

So when ever we are going deal with any Specific backup we need to know few use full parameters like control file, catalogue, sfile, restore , recover, database, mount, open ,sysadm, etc, etc.

C:\Documents and Settings\Administrator>rman target sys/XXX@dporacle nocatalog

RMAN-06005: connected to target database: DPORACLE (DBID=2406364181)

Database Backups Series - Part 1

Most challenging area for any backup tool administrator is Database backups.
Here we are going to discuss most of the database backups like oracle, sql,db2,sap,exchange  starting with oracle I am going to post my understandings on DB backups .

Example of simple rman cold backup in oracle DB:


ORACLE instance started.
Total System Global Area  1.007E+09 bytes
Fixed Size                    65484 bytes
Variable Size              86917120 bytes
Database Buffers          919568384 bytes
Redo Buffers                  73728 bytes
Database mounted.

C:\Documents and Settings\Administrator>rman target sys/xxxxx@dporacle nocatalo
Recovery Manager: Release - Production
RMAN-06005: connected to target database: DPORACLE (DBID=2406364181)
RMAN-06009: using target database controlfile instead of recovery catalog

RMAN> run {
2>   allocate channel t1 type disk;
3>   backup
4>     format '%d_t%t_s%s_p%p'
5>       (database);
6>    release channel t1;
7> }

Emc Legato networker MMINFO usefull TIPS

Here some of use full combinations of mminfo

Generally mminfo resides in /usr/sbin in unix, c:\programfiles\legato\nsr\bin in windows .

To query a client backup info for past 120 Hours:
/usr/sbin/mminfo -avot -c -t "-120 hours"

some times we can use grep effectively with networker command :
for example above command we can use in alternative way:

/usr/sbin/mminfo -avot -t "-120 hours" | grep -i

To Query a client backup info with ssid , size of saveset, tape info
mminfo -q "client=" -r "ssid,name,totalsize,savetime,volume" -t '60 hours ago'
