I have inherited a messy backup system. We have about 8TB of data to backup (6.5 GB for physical machines and 1.5GB for virtual machines). At the moment it’s backed up onto LTO Ultrium 4 data cartridge tapes (800 GB native tapes) using a 16 drive bay tape feeder drive and Symantec backup exec 2010 R3 for 7 physical servers and Veeam backup and replication 6.5 to back up 4 Virtual servers (Vmware VM's).
Backup Exec 2010 R3 - Runs a full backup on Friday evening and the backup takes some time to complete running well into Tuesday afternoon to complete and uses 9 tapes (possible will need 10 tapes soon). Incremental backups are run 3 times during the week on Tuesday, Wednesday and Thursday evening and use 3 tapes for each incremental backup.
Veeam backup and replication 6.5 – Runs a synthetic full backup on Saturday and incremental backups Sun/Mon/Tues/Wed/Thurs/Fri and stores the files on a ISCSI SAN
Also after the Veeam backups are run, Backup Exec is used to Backup some of the Veeam backup files onto the LTO Tapes (not all of Veeam data so bit of a messy setup)
The problem is the backups take to long to run, are difficult to manage, the tapes take to long to change over and restores are unreliable We would like to implement a new backup solution that ensure full backups have enough time to complete over the weekend without running into any working weekdays but not sure on what backup media & solution is best to use. We need a backup solution and media that is reliable and as quick as possible to backup and restore. We would prefer backup media that can be stored in a safe and taken offsite relatively easily and not sure if tape is best option.
Any suggestions on what we should do?
