Backup copy job scheduling

Post by blodsbror » Mar 07, 2015 5:36 pm

Case: 00824695

Hi,

I am still working on getting my Copy Jobs set up correctly (after reading all documentation), and have opened another case for this - I'm still yet to receive a reply, so thought I would put this to the forum as well. Just to give the figures, a Full backup of all data = 6TB (after 50% deduplication). And daily incrementals = around 600GB.

I have set the following for the copy job:

Copy every = 14 days @ 10am
Restore points to keep = 6
GFS quarterly backup = 2 (last day of the month of the quarter)

Does this mean I should have:

1. 3 months of backup copy retention, using 1 x 6TB + 5 x 600GB = 9TB of storage.
2. 6 months of GFS retention using 2 x 6TB = 12TB of storage. (Do, these get rotated as well every 3 months ?)

Thanks!

Hello,

Yees GFS restore points are stored as fulls, so you will have 12 TB + incremental restore points. After you reach the number of restore points configured by the retention policy, your oldest full (GFS backup) will be removed.

Thank you!

Hi,

I´m a little confused.. you mention that GFS restore points are stored as fulls, but then you mention "+incremental restore points" ?.
Also was my calculation below for regular restore points correct ? (I assume these are done with one full + incrementals) ?

Restore points to keep = 6
1. 3 months of backup copy retention, using 1 x 6TB + 5 x 600GB = 9TB of storage.

Many thanks!

These most recent restore points are stored as incrementals going from the most recent full backup file.

Yes, If simple retention policy is used (without GFS), then you will have 1 full and 5 increments at the end of the 3rd month.

Right, thanks. If GFS is also enabled, that doesn't disable the simple retention policy does it?

No, it does not, but your GFS restore points will be accounted in the configured retention policy settings.

Thankyou. So essentially, does the calculations from my initial post stand correct here, with a total of 21TB of required storage ?

Copy every = 14 days @ 10am
Restore points to keep = 6
GFS quarterly backup = 2 (last day of the month of the quarter)

Does this mean I should have:

1. 3 months of backup copy retention, using 1 x 6TB + 5 x 600GB = 9TB of storage.
2. 6 months of GFS retention using 2 x 6TB = 12TB of storage
