When does your NetBackup version reach end of support, and what is the latest version? The product lifecycle table on the SORT site (last updated 9 November 2026) lists NetBackup 11.2.0.1, released on 8 September 2026, as the latest release. Every release gets an End of Support Life (EOSL) date (the newest, 11.2.0.1, does not have one yet), and only the most recent maintenance version in each release cycle (for example 10.5.0.1, not 10.5) gets extended and sustaining support. NetBackup is a Cohesity product (formerly Veritas); its lifecycle data is still published on SORT.

How the NetBackup support phases work

The product lifecycle policy describes three phases before EOSL:

Primary: full support, including bug fixes and patches.
Extended: technical support continues, but only existing fixes and patches are provided, plus limited critical security vulnerability fixes. It is a paid add-on sold in one-year increments.
Sustaining: reduced support, limited to existing fixes, with no new bug fixes, patches or security fixes. Also a paid add-on.
EOSL: no support of any kind.

In the SORT table, a base release such as 10.5 goes straight to EOSL three years after its release date. Its last maintenance release (10.5.0.1) moves into extended support on that same date, into sustaining support two years later, and reaches EOSL a year after that.

NetBackup EOSL dates for current releases

Dates for NetBackup Enterprise Server, from the SORT EOSL table:

Version	Released	Extended support starts	Sustaining support starts	EOSL
11.2.0.1	8 Sep 2026	To be determined	To be determined	Not yet set
11.2	28 May 2026	Not applicable	Not applicable	28 May 2029
11.1.0.2	23 Feb 2026	24 Nov 2028	24 Nov 2030	24 Nov 2031
11.0.0.1	12 Aug 2025	18 Mar 2028	18 Mar 2030	18 Mar 2031
10.5.0.1	22 Jan 2025	30 Sep 2027	30 Sep 2029	30 Sep 2030
10.4.0.1	17 Jun 2024	27 Mar 2027	27 Mar 2029	27 Mar 2030
10.3.0.1	15 Jan 2024	23 Oct 2026	23 Oct 2028	23 Oct 2029
10.2.0.1	19 Jun 2023	31 Mar 2026	31 Mar 2028	31 Mar 2029
9.1.0.1	7 Sep 2021	7 Jun 2024	7 Jun 2026	7 Jun 2027

Base releases end earlier: 10.3 reached EOSL on 23 October 2026, 10.4 follows on 27 March 2027 and 10.5 on 30 September 2027. SORT lists appliances, agents and options separately, so check each component you run.

What this means for GCC customers

As of today, every 10.x maintenance release up to 10.3.0.1 is in extended support, so they receive no new bug fixes. 9.1.0.1 is in sustaining support and receives no new security fixes. If you are still on 10.3 or an older base release (10.0 to 10.2), you are already past EOSL.

This matters most for regulated organisations. If your auditors or regulator ask whether critical systems run vendor-supported software, a backup platform in extended or sustaining support is hard to defend. Security is the other reason: when Cohesity fixed the console vulnerability in our post on NetBackup security advisories and the 11.2 upgrade, the fix was to upgrade to 11.2 or later.

Timing is the practical constraint. Many organisations in the region freeze changes around year-end, audits and peak business periods, so 10.4's EOSL on 27 March 2027 can leave fewer usable windows than it seems. Older estates may also need extra work: the NetBackup 11.2 Upgrade Guide does not cover the required steps for EOSL versions, so upgrading from one means also reviewing the guides for each release in between.

How to plan a NetBackup upgrade

Inventory every component: primary servers, media servers, clients, appliances and agents, with exact versions.
Check each version against SORT and the NetBackup compatibility lists.
Pick the target release with the longest runway that your compatibility checks allow.
Respect the version order. Mixed versions are supported, so you can upgrade one server at a time. Cohesity's compatibility guidance sets the version order as Snapshot Manager, primary server, media servers, then clients: each must run the same or a newer version than the ones after it. A media server that runs catalog backups must match the primary server's version.
Review your support contract before any version enters extended support. Our renewals team can quote the support you need.
Test a restore after each stage.

Our NetBackup engineers can assess your estate and plan the upgrade, and our Cohesity team can help if you are reviewing the wider platform.
