Since RDS snapshots are incremental, this new metric shows the total size of all blocks making up a snapshot (both directly stored and referenced blocks), distinct from the incremental snapshot size that only counts newly changed blocks. The feature is available across all RDS instances in all commercial AWS Regions via console, CLI, or SDKs. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What does the FullSnapshotSizeInBytes field in the Amazon RDS DescribeDBSnapshots API show? It shows the total size of all blocks that make up a given RDS snapshot, including blocks stored directly in that snapshot plus blocks referenced from previous snapshots. For example, a 100 GB volume with 50 GB of actual data would show a full snapshot size of 50 GB, whether it's the first snapshot or a later one. This differs from incremental snapshot size, which only counts newly changed blocks stored in that specific snapshot. _Track new AWS API fields like this on daily.dev to keep RDS backup cost estimates accurate._ ### How is Amazon RDS full snapshot size different from incremental snapshot size? Full snapshot size represents the total size of all blocks composing a snapshot, including both new blocks and those referenced from earlier snapshots, while incremental snapshot size only reflects the newly changed blocks stored in that particular snapshot. RDS snapshots are incremental by design, so most snapshots after the first only store modified blocks, making the full size metric useful for understanding true data footprint. _Developers reasoning about RDS storage costs can follow API changes like this via daily.dev._ ## Similar posts on daily.dev - [Amazon RDS now provides visibility into storage volume initialization status](https://daily.dev/posts/amazon-rds-now-provides-visibility-into-storage-volume-initialization-status-fphgrpfa5) · AWS · 0 upvotes · 0 comments - [Amazon RDS enhances observability for snapshot exports to Amazon S3](https://daily.dev/posts/amazon-rds-enhances-observability-for-snapshot-exports-to-amazon-s3-vvz5eftte) · AWS · 0 upvotes · 0 comments - [Amazon Redshift reduces manual snapshot cost for Serverless and RG instances](https://daily.dev/posts/amazon-redshift-reduces-manual-snapshot-cost-for-serverless-and-rg-instances-z3okefqe9) · AWS · 0 upvotes · 0 comments - [Understanding how backups work in Amazon Aurora](https://daily.dev/posts/understanding-how-backups-work-in-amazon-aurora-btxdcfqe4) · AWS Database Blog · 0 upvotes · 0 comments - [Amazon RDS for Oracle now supports cross-account snapshot sharing with additional storage volumes](https://daily.dev/posts/amazon-rds-for-oracle-now-supports-cross-account-snapshot-sharing-with-additional-storage-volumes-9youcfcjz) · AWS · 0 upvotes · 0 comments --- Tags: [#aws](https://daily.dev/tags/aws), [#backend](https://daily.dev/tags/backend) [View this post on daily.dev](https://daily.dev/posts/amazon-rds-now-adds-full-snapshot-size-information-to-the-console-and-api-plqepghmy) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Amazon RDS now adds full snapshot size information to the Console and API","url":"https://daily.dev/posts/amazon-rds-now-adds-full-snapshot-size-information-to-the-console-and-api-plqepghmy","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/amazon-rds-now-adds-full-snapshot-size-information-to-the-console-and-api-plqepghmy"},"datePublished":"2026-09-29T22:03:55.555Z","dateModified":"2026-09-29T22:04:15.713Z","description":"Amazon RDS now exposes the full snapshot size for database snapshots via a new 'FullSnapshotSizeInBytes' field in the DescribeDBSnapshots API and a...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/2882c7c17d66df165856646dee063081?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/2882c7c17d66df165856646dee063081?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"AWS","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"AWS","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/aws","url":"https://daily.dev/sources/aws"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/amazon-rds-now-adds-full-snapshot-size-information-to-the-console-and-api-plqepghmy","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"aws,backend","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"AWS","item":"https://daily.dev/sources/aws"},{"@type":"ListItem","position":3,"name":"Amazon RDS now adds full snapshot size information to the Console and API"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/amazon-rds-now-adds-full-snapshot-size-information-to-the-console-and-api-plqepghmy#faq","mainEntity":[{"@type":"Question","name":"What does the FullSnapshotSizeInBytes field in the Amazon RDS DescribeDBSnapshots API show?","acceptedAnswer":{"@type":"Answer","text":"It shows the total size of all blocks that make up a given RDS snapshot, including blocks stored directly in that snapshot plus blocks referenced from previous snapshots.
