Слайд 3

General tape information
Sequential read/write access, long seeking times
Long-term storage (15-30 years)
H/W

compression and encryption
LTO (Linear Tape-Open) is the most widely adopted standard

Слайд 4

Devices
Standalone tape drive
Load/unload operations are handled manually by the user
Tape library

(automated changer)
Has one or more tape drives connected to it
Automatically puts tapes from slots to drives, and returns them back

Слайд 6

Veeam requirements for tapes
LTO-3 tape drives/libraries and newer
Directly connected to a

“Veeam Tape Server” over SCSI, SAS or Fibre Channel
iSCSI is rarely used, but also fine, even for virtual servers
Vendor drivers for library and tape drives are recommended, but native SCSI commands mode is also possible (v9)
v8: Vendor drivers are required
Non-exclusive mode for the drivers
No 3rd party tape solution interfering

Слайд 7

Job types
File to tape (Standard license)
Copy any files from any server

to tape
Basic VSS is possible (this way locked files can be copied)
Backup to tape (Enterprise license)
Pick backup jobs or whole repositories
Only .vbk and .vib files are processed
Synthetic full for forever incremental Backup jobs
GFS tape jobs (v9)
Creates archives for source VMs according to GFS scheme
GFS media pool should be a target

Tape Backup process

Слайд 10

Media pool
A collection of tapes designated as target for a job
Retention

applies on a media pool level
Built-in pools: Free, Unrecognized, Imported, Retired.

Слайд 11

Media set
Set of tapes used for continuously writing backup data (specific

time period)
Helps to distinguish data (append or not append)
Backup set - the set of files that are archived to tape within one tape job session

Слайд 12

Retention
Applies to tapes in a media pool
Options:
Never overwrite data
Protect for N

days
Do not protect data

Слайд 13

Media Pool: New in v9
Global Media Pools
Span tapes belonging to multiple

libraries
Possible to move tapes b/w libraries without cataloging them
Parallel Processing
Parallel writing to the same Media Pool
Process simultaneously several tape jobs or several backup jobs
GFS Media Pool
Keeps four predefined media sets: Weekly, Monthly, Quart., Yearly
GFS job produces only full backups and starts only on GFS days
Manual Active Full is possible for GFS jobs

Слайд 14

Media selection logic
Protection enabled
Tape Online
Take with expired protection
Create new media set

for every backup session
Take the tape that was written previously
Find first free (alphanumerically)

Take online

Yes

Слайд 15

Media selection logic
Online and not write protected tapes are taken
2.1

If create new Media Set is NOT checked, job tries to get the one, that was written last time
2.2 If create new Media Set IS CHECKED, job finds first free (out of online and not protected in this Media Pool ). Ordered by barcode, then by display name (alphanumerically)
3.1 If the Media Pool has OVERWRITE PROTECTION ENABABLED, job finds a tape where protection is over
3.2 If DO NOT PROTECT is set, job tries to capture tape from free pool, if Media Pool settings allows
