OS Backups By PSI Legato

Linux

We are exploiting the official PSI backup system "Legato" by installing and configuring the Linux client like well described in this PSI How To.
Please follow those instructions first and if they are not enough then invest time by also reading this Wiki page.

Backuped Hosts

We've decided to backup the following systems:

• t3admin01
• t3cmsvobox02
• t3ce02
• t3ui04
• t3fs13
• t3fs14
• t3se01
• t3dcachedb03
• t3dcachedb04
• t3wn20

Recover files by CLI - recover

You can browse and recover the backup of a file or directory for the server X by logging by SSH in X and using the command 'recover', follows an example of its usage on the server t3wn20:

[root@t3wn20 tmp]# recover -d /tmp/prova -s bs1
Current working directory is /tmp//
recover> ?
6477:recover: Available commands are:
   add [-q] [filename] - add `filename' to list of files to be recovered
   cd [dir] - change directory to dir
   changetime [date | -l locale_date] - change the time that you are browsing, changetime [-l] displays the supported [[locale_]date] format
   debug
   delete [filename] - delete `filename' from the recover list
   destination - print destination location for recovered files
   dir [/w] [filename...] - list filename
   exit - immediately exit program
   force - overwrite existing files
   help or `?' - print this list
   lf [-aAcCdfFgilLqrRsStu1] [filename...] - list filename type
   list [-c | -l]  - list the files marked for recover
   ll [-aAcCdfFgilLqrRsStu1] [filename...] - long list filename
   ls [-aAcCdfFgilLqrRsStu1] [filename...] - list filename
   noforce - do not overwrite existing files
   pwd - print current directory
   quit - immediately exit program
   recover - recover requested files
   relocate [dir] - specify new location for recovered files
   verbose - toggle verbose mode; feedback about what is going on
   versions [filename] - report on each version of file `filename'
   volumes [filename] - report volumes needed to recover marked files
6478:recover: `filename' can be either a file or a directory

Recover files by GUI - nwrecover

Ww can also browse and recover backuped files and dir by using the graphical GUI 'nwrecover', to start it run a command like:

[root@t3wn20 tmp]# nwrecover -s bs1

and you'll enter in the GUI browsing the latest available backup for the server t3wn20.

Installation Files

You can find the installation file here:

[root@t3admin01 home]# ll /root/legato-backup-clients/
