Does the E-Tech CloudBAK client run as a service?
The E-Tech CloudBAK client runs as an application but E-Tech CloudBAK proprietary scheduler runs as a service.
Does E-Tech CloudBAK encrypt my data?
Yes, E-Tech CloudBAK automatically compresses and encrypts (up to 256 AES encryption) your data before it leaves your machine.
Does the data on the E-Tech CloudBAK vault rest encrypted?
Yes, all data is compressed, de-duped and encrypted BEFORE leaving the machine where the E-Tech CloudBAK client is installed. Once the data reaches the vault it will rest fully encrypted.
Is there a no compression option?
Yes. Although compression is on by default, you can choose to disable it from within your backup job creation.
Is there a no encryption option?
Yes. Although encryption is on by default, you can choose to disable it from within your backup job creation.
Note: Once encryption is disabled for a specific backup job, you will NOT be able to re-enable it for that specific profile and instead would have to create a new profile with encryption ON.
What is the difference in compression levels and when should I use what?
Best Compression:
This option will use the best compression available for the ZLIB compression library.
When would this be used:
This option would be used if you have a slower internet connection and want to maximize your transfer.
Default Compression:
This option will use medium compression for the ZLIB compression library.
When would this be used:
This option would be used if you have an average internet connection.
Best Speed:
This option will use hardly no compression from the ZLIP compression library.
When would this be used:
This option would be used if you have a very fast internet connection.
No Compression:
This option would be used if you have a very fast internet connection and don’t have any cap on it.
When would this be used:
This option would be used if you are going across the local LAN.

Can we connect to all machines under a Domain with a global ID and password?
Yes. To do so from within the E-Tech CloudBAK Client, select the Domain ID and Click Set a Global Log in. This will automatically connect and authenticate all the children machines within the Domain.
Does E-Tech CloudBAK use client listener programs on each workstation?
No, you only need to install E-Tech CloudBAK on 1 machine and then use your existing network to connect into each other computer. You can also install the E-Tech CloudBAK client on each machine to connect that way as well.
What happens if the E-Tech CloudBAK client loses its internet connection during backup?
If the E-Tech CloudBAK client loses its internet connection, the executive client will automatically try to reconnect itself back to the server until it reaches its predefined amount of reconnects. To change the number of retry attempts, visit the preferences within the E-Tech CloudBAK client.
What ports must be opened in my firewall to allow backups to the E-Tech CloudBAK Server?
You need to configure your firewall to allow access to the following ports:
2430,3333,3334,3335,3336,3337,3338
Backup Profiles
How do I delete a backup profile from my client machine?
1. Start the E-Tech CloudBAK Client
2. Click on Edit Backup Schedule
3. Select the backup profile you would like to delete
4. Click Delete selected profile
5. Done
Does E-Tech CloudBAK dedupe when running local storage backups?
Yes, E-Tech CloudBAK dedupes when it performs both local and remote backups.
What is deduping?
Deduping means removing duplicate entries in a set. E-Tech CloudBAK utilizes block level de-duping technology automatically.
For example if you have 100 machines that are backing up calculator.exe (which has lets say 2 blocks), only the first machine will backup that file and transfer it to the server. The other 99 machines will simply skip the 2 blocks, calculator.exe, because the 2 blocks will already reside on the E-Tech CloudBAK server.
References to the files will always be kept for all backups, but only unique data is actually stored.
How does max generation work?
If backups are set to keep 5 generations, then you’ll always have 5 valid generations.
We will only remove a generation if there is X valid generations (x is the value you define in the Executive Client)
Valid generation definition: Success or Success with Exceptions
Ex) Let’s say you set your generations to keep a maximum of 5:
Day 1) invalid version
Day 2) valid
Day 3) valid
Day 4) valid
Day 5) invalid
Day 6) valid
Day 7) valid
Day 8) valid <—- Remove Day 1 and Day 2
Day 9) valid <—- Remove Day 3
Day 10) valid <—- Remove Day 4
Day 11) valid <—- Remove Day 5 and Day 6
How does max generations work with MS SQL?
If backups are set to keep only 2 Thin Full generations and Keep 1 thin differential generations per thin full.
Day 1) Full Version
Day 2) Thin Version
Day 3) Full Version
Day 4) Thin Version
Day 5) Full Version <—- Remove Day 1 and Day 2
Day 6) Thin Version
How does max generations work with MS Exchange?
If backups are set to keep only 2 Thin Full generations and Keep 1 thin incremental generations per thin full.
Day 1) Full Version
Day 2) Thin Version
Day 3) Full Version
Day 4) Thin Version
Day 5) Full Version <—- Remove Day 1 and Day 2
Day 6) Thin Version
Backing Up MySQL
Can I run the E-Tech CloudBAK client on a different computer from the MS SQL server that I want to backup?
For LAN SQL backups, please verify the following:
1) If it is a scheduled backup, make sure the backup has a username/password specified. Otherwise the Backup Scheduler will use the local system account which does not have access to network resources.
2 i) If the SQL server is on the same domain as your backup client, then you should configure your backup client schedule to use a domain username/password.
2 ii) If the SQL server is not on the same domain as your backup client, then you need to use a schedule username and password that exists on both the backup client computer and the SQL computer.
3) Your MS SQL service should be configured to use the same username and password as mentioned in step 2. (i.e. it cannot run from the local system account for the same reason as mentioned in step 1. I.e. The local system account cannot access network resources).
Typical service name for MS SQL Full: MSSQLServer
Does a full SQL backup need to run before a THIN SQL backup?
Yes but when first creating the backup job, you should select THIN SQL and NOT Full Backup. This is because the E-Tech CloudBAK software will automatically perform a full backup before proceeding to use our THIN technology.
Does E-Tech CloudBAK perform incremental backups on my MS SQL at the delta block level?
E-Tech CloudBAK dedups the data for file backups, SQL backups and Exchange backups.
E-Tech CloudBAK does not only do file level deduplication, but it does block level deduplication.
Meaning if there are 2 blocks that are the same in both files, it will only back it up once, even if the filename or database name is different.
How much temp space does a MSSQL Server Backup need?
If the E-Tech CloudBAK Client cannot do a virtual dump of the MSSQL Server Databases, then it will require as much temp space as the biggest Database in the MSSQL Server you are backing up.
What is DBCC Check for MS SQL?
These statements check the physical and logical consistency of a database.
What is the difference between virtual and physical backup?
A virtual backup will perform the backup using RAM and only about 1KB of physical space for the config file.
A physical backup will dump the full backup to the hard drive and then backup up the dump file.
Which versions of MSSQL does E-Tech CloudBAK support?
E-Tech CloudBAK supports:
- MSSQL 2000 with Service Pack 4 + roll ups
- MSSQL 2005 with Service Pack 1 or greater
- MSSQL 2008 with Service Pack 1 or greater
Backing Up Exchange
Which versions of MSExchange does E-Tech CloudBAK support?
E-Tech CloudBAK supports Full Exchange backups for:
- MS Exchange 2000 with latest services packs
- MS Exchange 2003 with Service Pack 2 or greater
- MS Exchange 2007 with Service Pack 1 or greater
E-Tech CloudBAK supports Brick Level Exchange backups for:
- MS Exchange 2003 with Service Pack 2 or greater
- MS Exchange 2007 with Service Pack 1 or greater
Can I backup individual MS Exchange 2007 mailbox databases with VSS?
No, Microsoft Exchange Server 2007 only supports snapshot (VSS) for backing up the entire storage group.
How does Thin Exchange Backup work?
1. User specifies how many incremental(s) per full they would like to keep
2. For the first full backup, the whole exchange database will be processed and transferred.
3. For each incremental, only the changes will be processed and transferred.
4. If you specify to keep 30 incremental(s) per full, then on the 31st day a new full will be processed, but only the incremental changes since the 30th backup will be transferred.
5. Deletion rules work by specifying how many fulls and associated incremental(s) you would like to keep. So if you are keeping 30 incremental (s) per full, and you want to keep 3 fulls, then you would have at most 90 restore points.
6. Each restore point, whether it is full or incremental is a full restore point. You don’t need to manually restore from several different backups to get your exchange database back to how it was on any of these 90 restore points.
Ex)
Exchange runs daily and the date today is Dec 01, 2008. I specify to keep 1 full generation and 21 incremental.
Day 1 – Exchange Backup will perform a full database backup
Day 2 – Exchange Backup will perform an incremental backup
Day 3 through 21 – Exchange Backup will perform an incremental backup
Day 22 – Exchange Backup will perform a full database backup and deletes the old Exchange Full Backup and all associated incremental backups.
How much temp space does an MS Exchange Server Backup need?
If the E-Tech CloudBAK Client cannot do a virtual dump of the MS Exchange Server Databases, than it will require as much temp space as the biggest Database in the MS Exchange Server you are backing up.
What is a recovery storage group?
Recovery Storage Group is a new feature in Exchange 2003 and above. The advantage of using this is reduces the impact of restoring a single mailbox from backup. This will allow you recover a mailbox store without taking down your production database.
What is a Thin full Exchange Backup?
A full exchange backup is a complete backup that archives every selected database and all necessary log files.
E-Tech CloudBAK client would dump the full exchange database to virtual memory (or physical if can’t create virtual dump) and then dedup, encrypt, compress and then transfer the blocks that are needed on the server side
What is a Thin Incremental Exchange Backup?
A Thin Exchange Backup is a more efficient way to backup MS Exchange. A Thin Incremental Exchange backup will only back up the changes (log files) since the last full database backup. At restore time, the E-Tech CloudBAK Client will automatically merge the Thin Exchange backup(s) with the Full Exchange backup (.edb file) to restore the day in time requested by the user.
What is the difference between a full Exchange backup or a brick level backup
Exchange full backup: Will backup the entire Exchange server
Exchange brick level backup (mailbox level): Will allow you to choose which mailboxes to backup
What machine does E-Tech CloudBAK have to be installed on to run an exchange backup?
The E-Tech CloudBAK client can either be installed on the MS Exchange machine itself or on a remote machine.
E-Tech CloudBAK supports agentless MS Exchange backups.
