Слайд 3General 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
LTO (Linear Tape-Open) is the most widely adopted standard
Слайд 4Devices
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 6Veeam 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 7Job 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

Слайд 10Media 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.
Built-in pools: Free, Unrecognized, Imported, Retired.
Слайд 11Media 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
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 12Retention
Applies to tapes in a media pool
Options:
Never overwrite data
Protect for N
days
Do not protect data
Do not protect data
Слайд 13Media 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
Possible to move tapes b/w libraries without cataloging them

Слайд 14Media 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
No
Yes
No
No

Yes
Слайд 15Media 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
