Top Reports - Top 10 Accounts and Top 100 Blobs

3 min read

Cloud Storage Manager ships two pre-built ranked views that are the quickest path to cleanup decisions: the top 10 storage accounts by size, and the top 100 blobs by size, both tenancy-wide.

Where to find them

Click the Reports tab in the left navigation. The two top reports are at the top of the page.

Top 10 storage accounts

The 10 largest storage accounts across all your connected subscriptions, ranked by total size. Columns:

Account name
Subscription
Region
Total size (GB or TB)
Growth — change vs the previous scan period.
Tier mix — percent of the account's data in Hot / Cool / Archive.

A pie chart at the top shows what fraction of total tenancy storage these 10 accounts account for. For most tenancies the top 10 accounts represent 50 to 80% of the total bill — meaning a handful of accounts are where any cost-optimisation effort will pay off.

Common workflows:

Identify the top 3-5 accounts and investigate them in Storage Account Explorer for cleanup targets.
Look at the tier mix column. Accounts dominated by Hot-tier old data are prime candidates for lifecycle policies or manual tiering moves.
Compare growth between scans. Fast-growing accounts get a higher priority for tagging-strategy or lifecycle-rule rollout.

Top 100 blobs

The 100 largest blobs across the entire tenancy, ranked by size. Columns:

Blob name
Container
Storage account
Subscription
Size
Tier — Hot / Cool / Archive.
Last modified
Last accessed — if the account has access-time tracking enabled.

Common workflows:

Scroll the top. A handful of multi-GB blobs often account for a surprising fraction of total tenancy storage.
Sort by Tier ascending to find the largest blobs that are still in Hot tier — high-value tiering-move candidates.
Sort by Last accessed ascending to find the largest blobs nobody has read in months.
Right-click any blob to copy its URL, jump to it in the Storage Account Explorer, or apply tier-change actions in bulk.

Exporting

Both reports have an Export button producing a CSV with every shown column plus a few extras (blob ETag, MD5 hash, full URL). Useful for hand-off to a cleanup project owner or for downstream pivot in Excel.

Why 10 / 100?

The caps keep the reports at a useful size for human review. The top 10 accounts and top 100 blobs typically account for a majority of tenancy storage, which is the right scale for "review every line manually." For deeper-tail analysis, use the Storage Account Explorer sorted by size, or export per-account CSVs.
