Hi Community,
I’m using couchbase 6.5.1 community version. I have one query i have created Replication between two server’s buckets and its copying each other data continuously. I want to schedule replication on periodic manner fro example i want to replicate data every one hour instead of continuously.
Is there any functionality or method is there to achieve that.
Thanks in Advance 
Cheers,

XDCR is meant to be continuous, so there is no automatic/simple way to achieve what you would like to do.
However, you can try scripting xdcr replicate pause/resume commands and running the script via a cron. How well this works would be dependent on the behavior of your system – xdcr keeps xdcr checkpoint information to know which sequence number it last replicated for each vbucket. If the replication is paused for too long, and if the vbucket’s purge seqno (last seqno purged by compaction) > than the xdcr last checkpoint seqno, then that will trigger a restream of all mutations from 0 when xdcr replication is resumed. And, of course, you’ll need to figure out the time periods between pauses and resumes that works for your system, etc.
You can run xdcr replicate pause/resume commands using either couchbase-cli or REST API:

@hyunjuV Thank you 
@hyunjuV, I understand that top posting on an old thread is not a best practice but this reply is very close to what I was looking for and hence…
You explained “if the replication is paused for too long”. Can you help understand how long is too long?
And secondly, would it be correct to believe that when XDCR is paused, it does not accumulate the changes (mutations) in memory or in some cache or disk. It remembers just the last seqno and whenever XDCR is resumed, it simply starts scanning the data from that seqno (if still available) to resume replication?
Thanks
