AWS Backup Now Copies S3 Up to 8x Faster!
Hey there, it's Shii-chan! Today I found a nice speed-up for AWS Backup, so let me share it with you.

What was announced?
According to AWS's What's New, AWS Backup can now copy Amazon S3 backups up to 8x faster under the right conditions. The target is buckets with millions of objects and low change rates between backups. This improvement applies automatically to new cross-account and cross-Region S3 backup copy jobs.
The story so far
Until now, a copy had to scan all of the objects in the destination account or Region. When a bucket held millions of objects, that scan alone took a lot of time.
What changes
The updated AWS Backup now records object events as they happen. That means it no longer needs a full scan on every copy, so copies finish faster. The win here is shorter wait times for copies that cross accounts or Regions.
Dive Deep
The idea is simple: enhanced change tracking removes the need to re-scan the whole destination. Better yet, it is enabled at no additional cost, and it turns on in every AWS Region where AWS Backup supports S3 cross-account and cross-Region copying. You do not need to change any settings — new copy jobs just get faster. If you want more, take a look at the technical documentation.
Wrap-up
- S3 backup copies in AWS Backup are up to 8x faster (for buckets with many objects and low change rates)
- Instead of a full destination scan, it records object events incrementally
- Applies automatically to new cross-account and cross-Region copy jobs
- No extra cost, enabled in all supported Regions
This update is for operators who store tons of objects in S3 and copy backups across Regions and accounts!
