Backup Exec procedure

As before, we have around 250G data (mailboxes + data) for daily full backup by tape drive through Vertias Backup Exec 8.6.  (200G tape size, totally two tapes for each day, without auto loader).

In case, we must not accept the long time full backup in daily. So we intend to get a new backup schedule by Differential or Incremental.

Our plan:
Mon-Fri (Differential or Incremental)
Sat (Full backup)

However, we have a few problems for our new plan.

(Backup)
1. After we have run Full backup on Sat (by two tapes), if we run Differential or Incremental schedule on coming Mon-Fri,

- the differential data or incremental data will be appended on the second tapes ?
- the differential data or incremental data will be appended on one new tape only?
- the differential data or incremental data will be appended on the different new tapes ? I mean Monday’s Differential on Monday Tape, Tuesday's Differential on Tuesday Tape ?

2. The backup data is included "Mailbox" (Exchange) and data (File Server), but the mailboxes are also restored by Differential or Incremental method ?

3. Differential or Incremental, which one is the best one for a large amount of data ? Even just found another method - "Daily" – Files That Changed Today ?, is it also a good choice ?


(Restore)
4. If we restore a file from backup..
e.g. restore a file on Thu.

-  Put latest Full backup tape
-  And then put Mon, Tue, Wed, and Thu Tapes in sequence, right ?


Thanks help !

rhinoceros;

Just my opinions, but:

(1.)  Set up a media set defining the Overwrite/Append Protection times and turn Overwrite Protection fully on.  In the job definition, you can specify which media set to use and specify whether to append to media or overwrite.  Otherwise, it depends on how you rotate your media.  For instance, if you want to backup to the Monday tape on Monday, just put that tape in on Mondays and set its Overwrite protection time to 7 Days.  Then if you try to put the Monday tape in on that Wednesday, it will deny the overwrite operation.

(2.)  If you are backing up individual mailboxes, I expect the backup method will be the same as that of the files.  If you are backing up the Information Store, you can set the backup type in the Exchange tab of the job definition dialogue.

(3.)  Depends, if you want to have an easy life, go with the differential.  Restoring then only requires the last full backup and the last differential backup.  With incremental, you'll need the last full backup and all incremental backups since, in the correct order.  However, the more differential backups you do, the more tape you need, as you backup all files that have changed since the last full backup.  With incremental, tape usage is likely to be a lot less.  Forget 'Daily' -- if, for some reason, the backup routine is skipped for a couple of days, you'll not get a backup of the files that have changed since the last backup, only the files changed on the day the backup resumes.

(4.)  If you go with incremental, yes.  If you go with differential, you'd only need the latest full backup tape and Thursday's tape.

Many Thanks, J !


But would you mind to give me more commentary for my plan

Mail server+ File server backup (Full Backup w/ Incremental)
 
(Job Definition)
Job    Name     Job Type   Method             Overwrite       Time          
Job1  MailFull   Backup      Full                   Yes                Sat 00:00AM
Job2  FileFull    Backup      Full                   No                 Sat 04:00AM
Job3  Mail1-5    Backup     Incremental       Yes                Mon-Fri 00:00AM
Job4  File1-5     Backup     Incremental       No                 Mon-Fri 04:00AM


I want to clarify something as follow

1. The syntax of backup job is correct ?
Mail Full + FileFull store on “SAT” Tape together (one tape only), so job1 overwrite = Yes, job2 overwrite = No
Mail1-5 + File1-5 are also stored on one Tape together everyday (Monday’s tape, Tuesday’s Tape… totally 5 tapes), so job3 overwrite = Yes, job4 overwrite = No


2. These setting are correct ?
MailFull
(Microsoft Exchange Mailbox + Microsoft Information Store + System State)
(General Tab) Backup method for files: (FULL – Back Up Files – Reset Archive Bit)
(Exchange Tab) Backup Method: (FULL - Database & Logs (flush committed logs))

FileFull
(D drive)
(General Tab) Backup method for files: (FULL – Back Up Files – Reset Archive Bit)

Mail1-5
(Microsoft Exchange Mailbox + Microsoft Information Store + System State)
(General Tab) Backup method for files: (INCREMENTIAL– Changed Files – Reset Archive Bit)
(Exchange Tab) Backup Method: (INCREMENTAL – Logs (flush committed logs))

File1-5
(D drive)
(General Tab) Backup method for files: (INCREMENTIAL – Changed Files – Reset Archive Bit)

3. And I must take all Tapes for data restore as you said.
E.g. Wednesday’s file restores
Full Backup Tape (Sat Tape)  + Monday's Tape + Tuesday's Tape + Wednesday’s Tape


Thanks a lot !

Overwrite is required if you have media that is not yet allocated to a media set -- blank and scratch media will not be overwritten if Overwrite is set to false.  Personally, I would set up a media set with overwrite protection of 6 days, then set Overwrite to true.  The overwrite protection on the media set should prevent your incrementals from being overwritten until after a week has passed.

Otherwise, these settings seem correct.  You might want to back up EITHER the Information Store OR the mailboxes, as you're essentially backing up each mail item twice.

As for restoring, yes you will need Saturday's full tape, then all incremental tapes up to the desired day.
