Backup copy job scheduling

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!

Restore points to keep = 6

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

[Vitaliy S.]

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.

[blodsbror]

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

[Vitaliy S.]

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

Evan, your calculations are correct.

Thank you for that clear answer. What I was hoping to hear! Appreciated.
