Storage policy - Second copy ( AuxCopy ) retention spilt best practice

Question

Hello,I have a storage policy with an AuxCopy ( synchronous )  configured with the bewlo retention rules:7 days 1 CycleWeekly full - 30 DaysMonthly full - 90 Days I’m planning to create a another copy that will point to another data path to hold only the short-term retention ( 7 days 1cycle ), and to reconfigure the existing one to hold only the Weekly + Monthly full keeping the same retention days for those.How should I re-configure the exsiting copy?  Just remove the short retention rules ( 0 days 0 cycles ) and leave the extended retention rules for the weekly + monthly fulls as is ? Leave it as synchronous copy  or change it to selective ?Thanks

Hi ​@TNO,Step 1 – Identify the current synchronous copy libraryDetermine whether the library is a tape library or a disk library with deduplication enabled (dedupe storage pool).Step 2 – Decide on the target library for the new copyOption A: Use a different tape library.Option B: Use a new dedupe storage pool.⚠️ Important: You cannot select the existing dedupe storage pool that is already associated with the synchronous copy.Note:You can use the feature "Allow preemption between auxiliary copy jobs".Definition: Specifies that an auxiliary copy job can be preempted by another auxiliary copy job with a higher job priority.Default Value: 0 (for fresh installation) or 1 ((for upgraded CommServe with the RMAuxCopyInterruptAuxCopy Additional Setting enabled)Range: 0 (No) or 1 (Yes)Usage: When this parameter is enabled, you can preempt an auxiliary copy job with another auxiliary copy job, by setting a higher priority for the pre-empting auxiliary copy job.https://documentation.commvault.com/11.40/commcell-console/media_management_configuration_auxiliary_copy.htmlRegards,Wasim
