      Evidence Preservation

      Suspending Automatic Deletion

      Systems delete on schedules that nobody watches. A preservation duty does not pause them, and an instruction that stops a person from deleting has no effect on a policy running server-side at a fixed interval. Interrupting that policy is an administrative task with a deadline.

      The rule in short

      Once a preservation duty attaches, automated destruction has to be interrupted at the system level. That means suspending retention policies, disabling disappearing-message timers, halting backup rotation for the relevant period, and stopping the reimaging of devices. The federal rule contains no separate immunity for routine system operation; routine operation is only one factor in deciding whether a party took reasonable steps to preserve.

      Nothing in an information system waits for a legal decision. Mailboxes purge on a thirty-day cycle, chat channels expire on a timer, backup tapes rotate and overwrite, and a departing employee's laptop is reimaged within a week. Each of those processes is defensible in its own right, and each of them destroys evidence on a schedule that continues to run after a preservation duty has attached.

      Why systems delete by default

      Retention limits exist for reasons unconnected with litigation. Storage costs money, indexing large volumes slows systems down, privacy commitments promise that personal data will not be kept indefinitely, and a smaller data footprint reduces the harm of a security incident. Regulators in some sectors impose retention floors, but for most material outside those sectors the pressure runs the other way.

      The federal sanctions rule once addressed this directly. An earlier version provided that, absent exceptional circumstances, a court could not impose sanctions for information lost through the routine, good-faith operation of an electronic information system. That provision no longer exists. The current rule replaced it, and routine operation now enters the analysis only as a factor in deciding whether a party took reasonable steps once it anticipated litigation.

      The committee note accompanying the current rule is explicit that the prospect of litigation may call for intervening in routine operation. Read together, the effect is that ordinary deletion is unremarkable until a duty attaches and becomes a decision immediately afterward. The absence of a standalone immunity is the reason suspension has to be treated as an operational task with a deadline rather than a policy aspiration.

      The settings that have to change

      Suspension is carried out by administrators, not by custodians. A hold notice tells an employee not to delete; it does nothing about a policy that deletes on the employee's behalf. The two steps have to be taken together, and the second is invisible to everyone except the people who operate the system.

      Identifying the settings is harder than changing them. Most organizations run several platforms acquired at different times, each with its own retention model, and no single person knows all of them. A written inventory of where data lives and what destroys it is the precondition for any credible suspension, and building one during a dispute is slower and less complete than maintaining one in advance.

      SourceDefault behaviorWhat suspension requires

      Backup mediaRotation overwrites on a cycleRemove a set from rotation for the relevant window
      Departing employee devices and accountsReimaging and account deletion on exitExclude named individuals from the offboarding process

      Offboarding is the failure that recurs most often. A custodian leaves, the standard process runs, and a laptop is wiped weeks after a hold was circulated to a list that no longer included that person. The exclusion has to be built into the human resources workflow rather than handled by remembering, which is why the hold notice sent to administrators and records staff matters as much as the one sent to the team.

      A suspension that nobody verified is a suspension in name only

      Applying a hold in an administrative console does not always produce the expected result. Policies can be scoped to groups that a custodian has since left, a hold can be applied to a mailbox while the linked archive continues to purge, and a change can be reverted during an unrelated migration. Confirming after the fact that the material still exists is part of the reasonable steps, and it is the part most often skipped.

      Ephemeral and disappearing messages

      Platforms that delete content automatically after a short interval present the problem in its sharpest form. Where the timer is measured in hours, an organization that anticipates litigation has effectively no window in which to intervene, and by the time counsel is consulted the content is gone. Courts have treated the resulting loss as a consequence of a configuration choice rather than an accident.

      Two threads run through the decisions. The first concerns whether the platform was adopted or configured with litigation in mind, which bears on the separate question of the intent finding that unlocks the severest measures. The second concerns whether the organization, having chosen a platform without a hold capability, took any step at all once the duty attached — instructing employees to move relevant exchanges to a retained channel, exporting threads, or turning the feature off for the affected teams.

      Neither thread condemns short retention as such. Organizations adopt it for reasons that have nothing to do with evidence, and the rule does not require indefinite storage. The difficulty arises from the interaction between an automatic timer and a duty that attaches without notice.

      Backups and what they are worth

      Backups occupy an awkward position. They are usually duplicative, expensive to search, and maintained for disaster recovery rather than retrieval of individual records. Rule 26(b)(2)(B) allows a party to identify sources as not reasonably accessible because of undue burden or cost, and disaster-recovery media is the standard example.

      The usual compromise is to pull one set out of rotation covering the period in dispute and leave the remainder running. That preserves a restoration route at a bounded cost, and it gives a concrete answer to a preservation demand that asks for all backups indefinitely. Where a sector regulation already requires retention for a fixed term, the regulatory obligation runs alongside and is not displaced by the litigation duty.

      That protection weakens once live data has been lost. The current rule directs a court's attention first to whether the lost information can be restored or replaced through additional discovery, and a backup set is often the only candidate. A party that allowed live records to disappear and then rotated the backups that would have restored them has removed the cure as well as the evidence, which is a materially worse position than either failure alone.

      Documenting what was suspended

      The record of suspension is the evidence that reasonable steps were taken. What matters is specific: which policies were changed, by whom, on what date range of material, and what verification followed. Administrative tickets, console export logs and configuration change records serve this purpose better than a narrative written afterward.

      Timing is part of the record. A suspension applied the day a demand letter arrived reads very differently from one applied after a complaint was served, and the interval between the two is where any argument about loss will be located. Recording the request as well as the change captures that interval, including the cases where an administrator was asked promptly and the work took days to complete.

      The same record supports the opposite argument when a party contends that preservation was disproportionate to what the dispute actually required. A party urging that a preservation demand is excessive is expected to provide specifics about its systems, and it cannot do so without knowing what its own policies are. Documentation is therefore not only a defense against the measures available for lost electronic evidence but the raw material for negotiating the scope of preservation in the first place.

      Points to carry away

      • Automated deletion runs server-side and is unaffected by an instruction sent to custodians.
      • The current federal rule has no standalone safe harbor for loss caused by routine system operation.
      • Routine, good-faith operation remains a factor in assessing whether reasonable steps were taken.
      • Disappearing-message settings destroy content on a timer and are treated as a deliberate configuration choice.
      • Backup rotation overwrites on a cycle, so a hold has to reach the rotation as well as live systems.
      • The record of which policies were suspended, and when, is the evidence of reasonable steps.

      Questions readers ask

      Is using disappearing messages by itself improper?

      No. Organizations adopt short retention for legitimate reasons, including storage cost, privacy commitments and security exposure. The federal rule does not condemn a retention policy as such. What draws scrutiny is the failure to interrupt one after a duty to preserve attached, and the choice of a platform where interruption is technically impossible. Courts have distinguished between a policy applied evenly before any dispute and a setting changed or relied upon once litigation became foreseeable, which looks less like housekeeping and more like a decision about evidence.

      What happens if a vendor controls the deletion setting?

      The analysis follows control rather than ownership of the hardware. If a contract gives the organization the right to obtain records or to direct configuration, the records are generally within its control for discovery purposes, and it is expected to exercise that right. Where a platform genuinely offers no hold capability, that limitation is relevant to reasonableness but is not a complete answer, because the choice of platform was itself a decision. The practical step is to send the preservation instruction to the vendor in writing and keep the response.

      Do backups have to be preserved as well as live data?

      Not always. Backups are often duplicative of live systems, and preserving them at length is expensive. The usual approach is to suspend rotation for a defined window covering the relevant period, then argue proportionality about anything further. Backups matter most where live data has already been lost, because they may be the only route to restoration, and the federal rule directs attention first to whether lost information can be restored or replaced through additional discovery before any measure is considered.

      When the Duty to Preserve Begins

      The obligation to preserve evidence arises when litigation is reasonably anticipated rather than when a suit is filed. Federal Rule of Civil Procedure 37(e) presupposes that duty by asking whether information that should have been preserved was lost because reasonable steps were not taken. Anticipation is judged objectively on what an organization knew, and knowledge held by managers and counsel is generally attributed to the organization.

      Collecting Data Without Altering It

      An electronic record carries system-generated attributes that establish when it was created, who handled it, and where it sat. Ordinary copying overwrites several of them. Forensic imaging captures a bit-level duplicate and verifies it with a hash value; targeted collection captures defined items with their metadata intact; self-collection by custodians is the least reliable and the most commonly criticized. A chain-of-custody record documents each transfer.

      Ending a Litigation Hold

      A hold ends when the matter that created it is over and no other obligation covers the same material. That requires checking for appeals, related proceedings, regulatory retention periods and other holds on the same custodians before anything is released. The release itself is a written instruction reversing the original, and the record of what was held, collected and released is retained after the material itself is disposed of.
