Ben-Gurion University of the Negev was established in 1969 with the aim to bring Ben-Gurion University of the Negev was established in 1969 with the aim to bring development to the Negev, a desert area comprising more than sixty percent of the country. The University was inspired by the vision of Israel's first Prime Minister, David Ben-Gurion, who believed that the future of the country lay in this region. Today, Ben-Gurion University is a major center for teaching and research with campuses in Beer-Sheva, as well as in Eilat and Sede Boqer, where Ben-Gurion lived in his final years and is buried.

Filer to attached library OR (and? ) Filer to tsm server 2. Full + DIFFerential OR (and? ) Snapmirror TSM 6 gives a variety of backup options for NDMP. we have to decide which option best suits us.

With Ndmp backup over the net you can backup remote filer’s. For us it With Ndmp backup over the net you can backup remote filer’s. For us it was a significant advantage. The workload is on the backup storage.

Administrator's Guide 6. 2 page 253 -254 These are some of the features of Administrator's Guide 6. 2 page 253 -254 These are some of the features of NDMP backup. Features that had the most weight are: Migration and Reclamation Possible only in filer to server.

Full + DIFFerential Snapmirror • Full backups are done on a regular basis, for Full + DIFFerential Snapmirror • Full backups are done on a regular basis, for example, weekly • In between Full backups, Differential backups copy only files that have changed since last Full backup Snap. Mirror to tape dumps all current file data and all snapshot file data from the filer to local tape or filer-to-Tivoli Storage Manager Server TOC (Table of content) No TOC support Can restore singe file (with or without TOC) Enables the restore of all Snapshot copies back to the destination system • • Backup with TOC have the benefit of restoring single file without knowing the path of the file. But TOC take place in TSM database’s. Volume with many file’s on it take long time and database grow. Over time. The DIFFerential file backup grow in size and backup time

Example the difference of month backup with full + differential OR snapmirror Date Full+differntial Example the difference of month backup with full + differential OR snapmirror Date Full+differntial Snapmirror 01. 2011 Backup full Take snapshot 02. 01. 2011 Backup differential Take snapshot 03. 01. 2011 Backup differential Take snapshot ……… 31. 01. 2011 Backup differential Backup type=snapm Differential File level Snapshot block level At the end of the month the last differential file will be larger then the snapshot from the beginning of the month. In one backup operation you get the all month backups and the backup size will be the volume occupancy size.

In the tsm we see (occ) of the volume+snapshots. When we have to restore In the tsm we see (occ) of the volume+snapshots. When we have to restore we need the volume size on the netapp.
