Hi,
so, here is where you can perform a UTM restore:

if you don't click the "Point In Time" button, SMSQL will implicitly do a UTM restore.
However, please note that it will only replay logs which were previously backed up by a Full Backup or a Log only backup.
If you (at restore time) need a UTM including also the last minutes logs, I suggest you stop the connections to the SQL server, backup only the logs and perform the restore UTM as described above.
here is extra info from the IAG:
"How long do you want to retain transaction log backups on the source storage
system?
SnapManager needs transaction log backups to perform up-to-the-minute restore operations, which
restore your database to a time between two full backups. For example, if SnapManager took a full
backup at 8:00 a.m. and another full backup at 5:00 p.m, it could use the latest transaction log backup
to restore the database to any time between 8:00 a.m. and 5:00 p.m. If transaction logs are not
available, SnapManager can perform point-in-time restore operations only, which restore a database
to the time that SnapManager completed a full backup.
Typically, you require up-to-the-minute restores for only a day or two, which means you would
retain transaction log backups for one or two days."
hope that clarifies things.
