Using bpduplicate to create copy 2 with shorter retention time than primary copy
Our primary backups are stored in Puredisk on their local datacentre. We have a scheduled bpduplicate job that runs each night to create an offsite Copy 2 for each backup image in a Puredisk storage pool at an alternate datacentre. Retention on all images, copy 1 and copy 2, has been 1 month up until now.
However, we're a bit tight on space so I want to change the retention of the second copy for each image to be 1 week only. I can see that this should be achievable with the "-rl" switch and have read the command manual, which gives the syntax as:
-rl <retention_level> [,<rl-copy2>,....,<rl-copyn>]
...but I can't seem to translate that into a command that does what I want.
If I supply something like this:
bpduplicate -dstunit DC2-PD-STU -policy DC1-AD -hoursago 24 -rl 0
That changes the retention level on both copy 2 and the primary copy to one week.
I've also tried:
bpduplicate -dstunit DC2-PD-STU -policy DC1-AD -hoursago 24 -rl 3,0
That just gives me "invalid command usage".
Does anyone have a working example of this switch in use?
Thanks in advance (and sorry if I'm missing something really obvious!)
