Virtual TapeServer 8.2 Release Notes

Known Issues | 42
 Data Encryption automated key database backups do not log their backups to
the event.log file. For details on automated backups, consult the ks_backup.log file.
(TL-1001)
 Error message erroneously logged if the local copy of the key server backup
utility changes volumes and is placed in another vault. If the local copy of the key
server backup utility changes volumes and is placed in another vault, it may trigger a
critical error in the event log indicating a duplicate pool. This critical log entry can be
ignored. (TL-984)
 Non-Data Encryption systems do not indicate when cartridges are encrypted.
Encrypted cartridges will not show any indication of encryption if listed on a VTS that
does not have encryption enabled. (TL-977)
 Unmounted vaults may cause a key database restore to fail. If a vault is not
mounted, it may cause a key database restore to fail. (TL-951)
WORKAROUND: Remove the backup host and force a backup with the Backup to All
button. Then, restore using the Restore From Disaster Recovery button. After the restore
is successful, re-add the backup host.
 A corrupt key database backup can be propagated to all key database backup
hosts. If a key database backup is corrupted, the corrupt backup can be propagated to all
key database backup hosts. (TL-941)
WORKAROUND: Archive key database backups on a regular basis. Store archives
outside of the VTS environment to ensure that you can return to a working copy of the key
database in the unlikely event that the copy in use becomes corrupted.
 The ks_backup.log file may contain DOS line terminations. Some lines in the
ks_backup.log file contain DOS line terminations, which may appear as ^M if viewed with
certain editors. (TL-930)
VTSPolicy commands
 Memory issues occur when too many concurrent VTSPolicy migrations are
attempted. At most, one migrate per physical tape drive should occur at any one time.
(TL-6135, EAR 7280)
 Q_INC and Q_DIFF variables used in the CommVault VTSPolicy backup all
cartridges. Q_INC and Q_DIFF variables used in the CommVault VTSPolicy should
backup the changed cartridges since the last backup. Instead, all cartridges all in the pool
are backed up. (TL-2770)
 VTSPolicy TSM Archive command for a vault results in an error message.
Issuing a VTSPolicy TSM Archive command for a vault will fail to back up the vault. An
error message such as “Error: /VAULT00 not on this system” will be written to the VTS
log. (TL-221)
WORKAROUND: A vault may be backed up by issuing VTSPolicy TSM Archive
commands for the individual pools or cartridges in the vault.
