You are welcome! Maybe some deeper answers can help you more:
- disk to disk backups - Vinchin Backup & Recovery is VM level backup, is disk to disk
backup.
- inter-site replication with rate limiting - though Vinchin currently not support
physical server backup, next version in June will support file backup for physical
servers. is this inter-site replication request for your physical servers or virtual
servers?
- be able to handle Linux thin volumes (think RHGS) - be able to backup data to this RHGS?
or RHGS as a production storage? anyway,Vinchin can handle it in both.
- support BMR ans granular file / directory restore - file level restore of course
vinchin supported! but I really have no idea what is "BMR" you mentioned.
- correctly handle Windows VSS - application awareness, yes, vinchin supported!
- support RHEL point releases as soon as they are released - if you mean physical servers
running RHEL OS, oops! We can't help you. But if you mean the OS running in RHV and
Hyper-V, then all new point releases will be catched up with by Vinchin!
Hope my answer help you!
