Hi.
I got a server with only 2x 300 GB 10K SAS, 8 GB RAM & Quad Core CPU @ 2.4 Ghz only.
Attached to it is a Dell PV124T LTO6 SAS Auto Loader with 8 Magazine slot.
Full backup of four (4) server will only be around 2 TB (uncompress).
Backups should be written to tapes directly.
Can I configure my backup jobs this way
Daily Backups (Incremental or differential), retention is 7 days
Weekly backups (Full), retention is 4 weeks (28 days)
Monthly backups (Full), retention is 12 months.
My tapes should be dedicated to each type of backups.
Can I configure it this way: Each day must be assigned a slot.
Daily, Weekly & Monthly tapes should not be mixed. If a tape is used for Monday then it should only be used for Monday
If a tape is used for Full weekly backups on Saturday, no other backup data from other days should be appended to it.
For Slot 1 to 5, I plan just to leave the tapes on the autoloader.
For Slot 6, I will remove the tape weekly and replace with a different tape each week. There will be four (4) tapes assigned for weekly backups.
For Slot 7, I will remove the tape after a full backup that will be executed once a month (last Sunday of the Month). There will be twelve (12) tapes
Monday --> Slot 1 (Daily incrementals), Retention 7 days
Tuesday --> Slot 2 (Daily incrementals), Retention 7 days
Wed ---> Slot 3 (Daily incrementals), Retention 7 days
Thursday ---> Slot 4 (Daily incrementals), Retention 7 days
Friday ---> Slot 5 (Daily incrementals), Retention 7 days
Saturday ---> Slot 6 (Full weekly), Retention 28 days
Sunday ---> Slot 7 (Full monthly), Once a month, retention 12 Months
I would be open to suggestions and recommendations.
I'm also considering for Monday to Friday backups I will allocate around two (2) tapes. Incremental backups will be written to it daily. Backup data will be appended each day. So instead of having 5 tapes Monday to Friday, I will just use two tapes with a total of 5 TB capacity.
Thanks,
Paul
