How to check the retention of 2nd copy?

[King25may]

Hi,

I've changed the retention period of secondcopy for a backupid using the "bpexpdate -recalculate -backupid <bacckupid> -copy 2 -ret 9.

How can i check wether the retention changed or not?

If i use the "bpimagelist -U -backupid <backupid>" it is giving only the primary copies retention period.

Pls help

Or use the 'long' output with -L.

bpimagelist -L -backupid <ID>

[revarooo]

use -l instead of -U - this will show you your Fragment copy numbers. Expiration is 17th field.

Run: bpdbm -ctime <field 17 value>

bpdbm -ctime 1577836800

1577836800 = Wed Jan  1 00:00:00 2020

Or use bpimagelist -L backupid <backupid> like this:

bpimagelist -L -backupid test_server_1428388839 | awk '/Copy number/  {print} /^ Expiration Time/ {print}'

Hi,

I've attached the output of bpimagelist -L -backupid <backupid>.

In the result I can see all the copy number as 1.

There is a copy 2 as well with infinity retention

No wonder you could not find it....

1086 instances of 'Copy Number:' and more than 500 fragments in this backup image!! 
And this for backup of 633034828 Kbytes (+- 600 GB)?

Out of curiousity - what is the Fragment size in Storage Unit properties?

[King25may]

Hi Marianne,

Sorry for the delay. The fragment size is 10000 mb

[Marianne]

Maybe double-check and confirm. Seems to me it was a lot smaller when this backup and duplication was done.

PS: Nicolai has answered your query. Please mark his post as solution?

[revarooo]

Definitely something up with your fragment size on your storage unit - get that checked.

In the interest of this question, this works better, though not 100% perfect:

awk '/^ Expiration Time/ {print} /Copy number/ {print}' bpimage_0.txt | uniq

Copy number:       1
 Expiration Time:  Mon Jul  6 22:30:13 CDT 2015 (1436239813)
Copy number:       1
Copy number:       2
 Expiration Time:            INFINITY       (2147483647)
Copy number:       2

[King25may]

Can u give the command to find the fragments of storage unit?

So that I can double check

[Marianne]

bpstulist -L

Label:                LTO2_general_med05
Storage Unit Type:    Media Manager
Host Connection:      nmbpmed05

[Marianne]

Seems the fragment size was changed in the meantime.

Image output shows this:

Copy number:       2
 Fragment:         1
 Kilobytes:        540416

Which means fragment size was possibly set to 500 when the backup and duplication was done.

[King25may]

We didn't change the fragement size, I see  that for all the storage unit the fragment size is 10000.

[Nicolai]

Please check the fragment size again.  You shoud set fragment size to 50000 (50GB). This is Symantec Best Pratice for tape.

[King25may]

okay Nicolai.... Thank you
