How to do a full+diff chain that starts on a specific day?
I'd like to setup a backup schedule where:
Monday: full backup
Tuesday-Sunday: differential backup
Start: 5AM
If I define a custom scheme, I can specify that a full backup gets performed after 6 differential backups. Well, that covers 1 calendar week but won't ensure that the full backup always gets done at 5AM on Monday. Because months have variable days (28, 29, 30, 31), a simple 1+6 scheme means the full backup day will move around. I want it to always be on the same day.
I'm assuming that when I define a differential or incremental "chain" (not well described in the documentation) where every nth backup is a full backup has a full backup performed as the 1st backup, followed by n incrementals or differentials, and the pattern then repeats. That is a day-count based scheme, not a weekday based scheme.
If I define 2 backup schemes where a full backup is performed on Monday @ 5AM and another backup scheme where a differential backup is performed on Tuesday to Sunday @ 5AM (but the 2nd scheme does NOT specify doing a full backup, just differentials) will that work? That is, will the differential backups in the 2nd scheme (Tue-Sun) be based off the full backups in the 1st scheme (Mon)? Or do the separate backup scheme generate separate backup chains (so I'd get 1 full backup but an indefinite chain of differentials based off the first and only full backup for the 2nd scheme and the full backups in the 1st scheme aren't used by the differentials at all)?
On another note, is there a way to generate a grandfather-father-son scheme where once a month a full backup is performed, differentials are performed once a week (excluding the full backup day), and incrementals are performed every day (excluding the full and differential days)? Something like:
First Monday of every month: Full backup
Every Monday except the first one of the month: Differential backup (based off the full backup)
Every Tue-Sun: Incremental backup (based off the differential+full backup chain)

Then something got crippled in Acronis True Image Home. I used to have version 11 (still do on a CD for its installer but I haven't used it or had it installed for quite a long time). In that old version, I defined a full backup to run on Monday and incrementals to run on the other days. That worked as the differentials were based off the full backups. I didn't define "chains" or "backup schemes". I simply scheduled a full backup and scheduled incrementals (into the Secure Zone) and the "chains" got created okay. I'd get a weekly chain that spanned a full backup and all of its differentials.
This new version is still called "True Image Home" just like my old version. I figured it was still the same product. Looks like they crippled it or dumbed it down for noobs. So they pulled out the function that was available before to force their customers to buy the more expensive Workstation product. Oh wonderful. The upgrade cost from ATI Home v11 to ATI Home 2012 is $40. To upgrade from ATI Home v11 to Acronis Backup & Recovery Workstation (assuming that's even allowed) is $50. A big difference in expense just to get back a feature they removed from the Home edition.
If you're correct that I can longer create a full+differential schedule that starts on a specific day of the week then that's another negative score on Acronis True Image Home 2012. Upgrade and lose features (and get others that aren't critical, unwanted or fluff, or adware lures to buy more stuff from them).
UPDATE:
Hmm, it appears I had a similar question about ATI v11 regarding having a backup scheme where full were on a specify weekday followed by differentials on the other weekdays. Back then I was told it wasn't possible in v11 but someone came up with a utility (Chain2Gen). I really didn't like that solution since it meant I couldn't configure the backup scheme within ATI itself. If I have to resort to a patchwork solution then I start looking for a different solution.
Then I started to think about the scheduling available. Instead of defining a cyclic backup scheme (1 full + N differentials) which would end up wandering around as to what weekday on which the full would run, maybe I could define a differential scheme that ran once per month, like on the Nth Monday of the month.
I started to think about the following schedule of multiple differential chains. When a differential chain starts, it forces the first one to be a full backup. So maybe this would work:
- 1st Monday of the month: Differential = full backup + 6 differentials.
- 2nd Monday of the month: Differential = full backup + 6 differentials.
- 3rd Monday of the month: Differential = full backup + 6 differentials.
- 4th Monday of the month: Differential = full backup + 6 differentials.
The first problem I noticed with this is that sometimes there are more than 4 Monday is a month due to long months and the calendar week sliding around the day numbers of the month. There is a "Last of the month" choice but if there are only 4 Mondays then the Last Monday backup chain would overlap the 4th Monday backup chain. If I only do the above, and there is a 5th Monday in a month, that backup chain doesn't start and I don't have backups for a whole week. There is no "fifth" choice for running a monthly scheduled task. If there was, problem solved. If there was no 5th Monday of the month then there's no such backup that needs to be ran (since the 1st Monday of the month backup takes care of the next week). The only feasible setup would be:
- 1st Monday of the month: Differential = full backup + 6 differentials.
- 2nd Monday of the month: Differential = full backup + 6 differentials.
- 3rd Monday of the month: Differential = full backup + 6 differentials.
- Last Monday of the month: Differential = full backup + 6 differentials.
The problem that crops up with that setup is the 3rd Monday's backup set could extend for more than a week's worth of backups for a long month. If there were 5 Mondays in a month, the 3rd Monday backup set would cover that week plus the 4th Monday's backup set until the Last (5th) Monday came up. This means I'd have a backup set (for the 3rd Monday) that might be a bit longer than I care for. It could be almost 2 weeks in length in the last Monday was on the last day of the long month. But that's better than the full backup wandering all over the place.
Another problem I realized with the above is if the computer is unpowered for a day, or more. Each backup chain is defined to run 7 backups: 1 full followed by 6 differentials. If the computer were powered off for 2 days then the differentials get extended by another 2 days which overlap into the next week's differential chain. After all, you are not specifying on which days to run the differentials but only how many differentials there will be. There's no point in using the "run if missed" option when I startup Windows because there's already going to be a scheduled backup for that day when I powered up. I'd have to get the differential count shortened by the number of days the computer was powered down, and if zero of less then no differentials run since I've passed when the full backup should run (so I want a full backup instead of a differential based of an even older full backup).
The reason why I'm spurred in trying to get the backup chain to start on a particular weekday is that some operations will affect the size of a backup. If I run a defrag on the backed up partition, a differential or incremental backup could be almost as big as full backup. If, however, I schedule the defrag to run on Monday @ 1AM (the worst case is it runs for 3 hours so it ends at ~4AM, or earlier) then it has little effect on the following backup because the following backup on Monday is a full backup, anyway. I sync the scheduled defrag to run on the say day but prior to the scheduled full backup.
It seems odd that Acronis figures home users don't want the full backup for their backup chains to start on a particular day of the week. Why is this something that is relegated to only corporate users? Why is logic applicable in a corporate environment not also applicable in a home environment?

There is a possibility you could get TrueImage to do this--if you want to give it a try.
If you want the backup to begin each Monday with a full backup, it does not matter about variable days in month. Each Monday will be a full backup--assuming that your computer is operational 7 days each week. Any day computer is not run could be an issue and would need testing in order to find a work around.
Backup scheme would be custom/differential with 6 diff and keep x number of recent version chains. The X would represent x number of weeks backups to retain.
Set up One single task to run Weekly but checkmark each day so all days checked.
Backup task must be created after Sunday 6 a.m. or before Monday 5 a.m. Backup must be created after the Sunday scheduled time but before the Monday scheduled time. The "Backup later" would be option to save the task during creation.
Be absolutely certain to uncheck the Run backup if missed which is in the Advanced settings of the Scheduling screen. Scheduling example below.
sites/default/files/mvp/user285/guides/daily-via-week.gif
This is an example on how to set up the differential tasks which would be 1 full plus 6 differential. Change the 4 recent version chains to whatever number of weeks of backups (7 backups per chain) you wish to retain. Backup scheme example below.
sites/default/files/mvp/user285/2012-5545/2012-backup-scheme-dif.gif
If you need an additional full backup to be run monthly on the first Monday, the prior backup would be run at that time but if you need an additional single full Monday backup, you could set up an additional task and it could be run monthly. Scheduling example below.
sites/default/files/mvp/user285/guides/monthly-_on-_monday.gif
The use of Chain2Gen is still an excellent possibility. It is still available and in use by many.
Due to a lack of time, if the first Monday backup is missed, go ahead and create the task as suggested and when you get to the "Backup later" option, choose the "Backup now" option whatever times needed to get you onto the correct scheduled number of backups. First full would be late but the following Monday will be correct if the backup #7 runs on Sunday. Initially, Use extra manual "Backup now" in order to get the correct backup number running on a specific day.
If your computer not operational 7 days a week, you will need to run extra manual "Backup Now" to get your task onto the prescribed schedule so that the backup #7 (diff 6) ends on Sunday.

Well, I had a well-thought out reply but this stupid forum times out unless you generate an event before some idle threshold (idle for the forum but obviously not idle for the user keying in the contents of their post). Character input into a textbox doesn't generate an event. The result is that when I composed a reply while logged in but when I got to clicking Save the d*mn thing complained that I was not authorized - because it timed out my forum session. Apparently they expect their users to spend less than x minutes (where x seems pretty short) to do something in their forums. Auto-logouts SUCK!
So I'll be short this time (and be sure to copy my post before clicking Save in case my "short" is longer than their timeout).
Your one chain approach is better than mine. Mine would result in a missed 5th week backup chain or an extra long 3rd week backup. Your scheme happens to work for me because the first day of the week in ATI2012 happens to be the same first day of the week that I want: Monday. In Easeus ToDo Backup (for both their free and payware versions), their first day of the week is Sunday so I was stuck there doing weekly backup (on every day) with the 1st day being Sunday. For some users, it may be Sunday, or it might be Monday, or Friday, or Tuesday. Neither ATI nor ToDo let users define what is THEIR preference for the 1st day of the week. So what I have to do in ATI2012 is similar to what I had to do in ToDo Backup by selecting every day of the week in a weekly backup schedule. With ToDo, I was stuck with Sunday being the 1st day of the week. With ATI, I'm stuck with Monday (but that happens to be what I want - in this case).
Still there's the problem of backups in a chain extending into next week when another chain is supposed to start. I usually leave my computer on 24x7 but there are times when it is powered down for 1 day, or more, or even 2-3 weeks when I'm on vacations several times a year. I live at home. I don't work there. So the computer doesn't always have to be available at all hours just I happen to have an irregular sleep schedule. I'll need some way to abort/block the backups in a chain that would end up getting pushed into or overlapping with the next week's chain. Oh well, more thinking and stinking to do.

Even if you were to use Chain2Gen, it would miss its trigger day if the computer was down on Monday and would require a manual flag being set or it would not catch up until the next Monday (whenever) that the compute was on. C2G would keep making diff until a Monday appeared.
When you computer is off during a backup period, the only way Acronis can function for you would be for you to manually intervene and run the backups manually (backup now) until the number of chain backups is in sync with the schedule. If you are expecting automatic catchup, then it wood need to become custom software.
The Easeus ToDo Backup might work for you if you were to do your task creation and start your first backup on Monday--but I am not familiar with their software.
Good luck. I hope you find what you want.

You could kluge something together to make this work -- kind of... But just face it... If this is your requirement, then THI is not your tool. It sounds like a business requirement, so just spend the $$ for a SMB tool and be done with it.. or reevaluate your requirements.

iave acronois home set up to do a full backup and then 5 differential backups and then to do a full and 5 more diff etc etc
I set it to keep 4-5 sets.. and to start backup daily automatically. problem... keeps doing full backups

An incremental or differential backup task will always begin with a full backup.

Harvey,
Look the figure 11-Dif inside this link.
http://forum.acronis.com/forum/28705
Change the 6 to 5 if you want to create a full after 5 diff.
Leave the 4 as is if you only want to retain 4 sets of chains.
or, change the 4 to 5 if you want to retain 5 sets of chains (chain=1 full plus 5 diff)
Editing an existing task is NOT recommended as the results will be unpredictable.
Start a new task with the new settings pointing to a new empty sub-folder.
If you use automatic scheduling, Also be sure and look at figure 17 inside the link and make sure the advanced settings are properly set. Most likely, you do not want the backup to run at startup--if missed.
