Version control settings
This feature lets you gradually reduce the number of backed up versions over time to optimize storage within Cohesity Alta SaaS Protection.
By default, all versions are retained in Cohesity Alta SaaS Protection unless you enable the Version control feature.
Version control feature optimizes backup storage by keeping only the most relevant backed up versions and removing older, redundant ones.
The following retention settings are used to configure this feature for the selected Stor:
You must click this option to enable the version control feature.
Once this feature is enabled and the configuration is saved, it cannot be disabled. Also, the following default settings can only be edited once.
Table:
Settings | Time period | Pruning action | Retention strategy |
|---|---|---|---|
: | First 14 Days | No pruning occurs. | All newly added versions are retained. |
: | Day 15 to Day 105 (Next 90 Days) | Pruning starts; scans from feature enablement date. | Only one daily version is retained. |
: | Day 106 to Week 52 (Next 52 Weeks) | Further pruning occurs. | Only one weekly version is retained. |
: | After 52 Weeks to 240 Months | Final pruning phase. | Only one monthly version is retained for long-term storage. |
After 240 months, for versions beyond all retention periods (daily, weekly, and monthly), only the latest version will be retained, and all other versions will be pruned based on the last modified date.
Starting from Cohesity Alta SaaS Protection version 2.36.2, version pruning for versions beyond all retention periods is disabled for SharePoint Online.
Note:
For each time period, the backed-up version retained depends on whether the Stor supports versionings at the source. In Cohesity Alta SaaS Protection, SharePoint and Box are the two Stors that can have backed up items which are versioned at source. For example, a SharePoint Stor can have backup copies all versions of an item that are also present in a SharePoint Document Library that supports versioning.
: For a given time period, the most recent backed-up version (based on the archived time) is retained, and the rest are pruned.
Example: From day 15 to day 105, when only one version is retained per day, the most recent backed-up version from all item modifications on that day is retained.
: For a given time period, the version with the highest version number, as per the source, is retained, and the rest are pruned.
Example: From day 15 to day 105, when only one version is retained per day, the version with the highest version number from all item modifications on that day is retained.
SharePoint scenario: If a file in a versioned SharePoint Document Library was modified three times in a day, creating versions 8, 7, and 6, and all these versions were backed up, the Version Control feature in Cohesity Alta SaaS Protection will retain only version 8 for that day.
This behavior applies from the Cohesity Alta SaaS Protection 2.36.2 release.
Note:
For SharePoint, for a given time period, if the version to be considered for retention is less than 1 KB, pruning action is not done for all the versions in that batch for the item, when executing the retention strategy. This behavior is applicable from 2.36.2.
Note:
If a file is modified multiple times within the same day and the most recent changes occur within a span of a minute, Cohesity Alta SaaS Protection may retain any one of those versions. This behavior is applicable for any version control behavior before the Cohesity Alta SaaS Protection 2.36.2 release.
